/**
 * struct rtnl_link_stats64 - The main device statistics structure.
 *
 * @rx_packets: Number of good packets received by the interface.
 *   For hardware interfaces counts all good packets received from the device
 *   by the host, including packets which host had to drop at various stages
 *   of processing (even in the driver).
 *
 * @tx_packets: Number of packets successfully transmitted.
 *   For hardware interfaces counts packets which host was able to successfully
 *   hand over to the device, which does not necessarily mean that packets
 *   had been successfully transmitted out of the device, only that device
 *   acknowledged it copied them out of host memory.
 *
 * @rx_bytes: Number of good received bytes, corresponding to @rx_packets.
 *
 *   For IEEE 802.3 devices should count the length of Ethernet Frames
 *   excluding the FCS.
 *
 * @tx_bytes: Number of good transmitted bytes, corresponding to @tx_packets.
 *
 *   For IEEE 802.3 devices should count the length of Ethernet Frames
 *   excluding the FCS.
 *
 * @rx_errors: Total number of bad packets received on this network device.
 *   This counter must include events counted by @rx_length_errors,
 *   @rx_crc_errors, @rx_frame_errors and other errors not otherwise
 *   counted.
 *
 * @tx_errors: Total number of transmit problems.
 *   This counter must include events counter by @tx_aborted_errors,
 *   @tx_carrier_errors, @tx_fifo_errors, @tx_heartbeat_errors,
 *   @tx_window_errors and other errors not otherwise counted.
 *
 * @rx_dropped: Number of packets received but not processed,
 *   e.g. due to lack of resources or unsupported protocol.
 *   For hardware interfaces this counter may include packets discarded
 *   due to L2 address filtering but should not include packets dropped
 *   by the device due to buffer exhaustion which are counted separately in
 *   @rx_missed_errors (since procfs folds those two counters together).
 *
 * @tx_dropped: Number of packets dropped on their way to transmission,
 *   e.g. due to lack of resources.
 *
 * @multicast: Multicast packets received.
 *   For hardware interfaces this statistic is commonly calculated
 *   at the device level (unlike @rx_packets) and therefore may include
 *   packets which did not reach the host.
 *
 *   For IEEE 802.3 devices this counter may be equivalent to:
 *
 *    - 30.3.1.1.21 aMulticastFramesReceivedOK
 *
 * @collisions: Number of collisions during packet transmissions.
 *
 * @rx_length_errors: Number of packets dropped due to invalid length.
 *   Part of aggregate "frame" errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter should be equivalent to a sum
 *   of the following attributes:
 *
 *    - 30.3.1.1.23 aInRangeLengthErrors
 *    - 30.3.1.1.24 aOutOfRangeLengthField
 *    - 30.3.1.1.25 aFrameTooLongErrors
 *
 * @rx_over_errors: Receiver FIFO overflow event counter.
 *
 *   Historically the count of overflow events. Such events may be
 *   reported in the receive descriptors or via interrupts, and may
 *   not correspond one-to-one with dropped packets.
 *
 *   The recommended interpretation for high speed interfaces is -
 *   number of packets dropped because they did not fit into buffers
 *   provided by the host, e.g. packets larger than MTU or next buffer
 *   in the ring was not available for a scatter transfer.
 *
 *   Part of aggregate "frame" errors in `/proc/net/dev`.
 *
 *   This statistics was historically used interchangeably with
 *   @rx_fifo_errors.
 *
 *   This statistic corresponds to hardware events and is not commonly used
 *   on software devices.
 *
 * @rx_crc_errors: Number of packets received with a CRC error.
 *   Part of aggregate "frame" errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter must be equivalent to:
 *
 *    - 30.3.1.1.6 aFrameCheckSequenceErrors
 *
 * @rx_frame_errors: Receiver frame alignment errors.
 *   Part of aggregate "frame" errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter should be equivalent to:
 *
 *    - 30.3.1.1.7 aAlignmentErrors
 *
 * @rx_fifo_errors: Receiver FIFO error counter.
 *
 *   Historically the count of overflow events. Those events may be
 *   reported in the receive descriptors or via interrupts, and may
 *   not correspond one-to-one with dropped packets.
 *
 *   This statistics was used interchangeably with @rx_over_errors.
 *   Not recommended for use in drivers for high speed interfaces.
 *
 *   This statistic is used on software devices, e.g. to count software
 *   packet queue overflow (can) or sequencing errors (GRE).
 *
 * @rx_missed_errors: Count of packets missed by the host.
 *   Folded into the "drop" counter in `/proc/net/dev`.
 *
 *   Counts number of packets dropped by the device due to lack
 *   of buffer space. This usually indicates that the host interface
 *   is slower than the network interface, or host is not keeping up
 *   with the receive packet rate.
 *
 *   This statistic corresponds to hardware events and is not used
 *   on software devices.
 *
 * @tx_aborted_errors:
 *   Part of aggregate "carrier" errors in `/proc/net/dev`.
 *   For IEEE 802.3 devices capable of half-duplex operation this counter
 *   must be equivalent to:
 *
 *    - 30.3.1.1.11 aFramesAbortedDueToXSColls
 *
 *   High speed interfaces may use this counter as a general device
 *   discard counter.
 *
 * @tx_carrier_errors: Number of frame transmission errors due to loss
 *   of carrier during transmission.
 *   Part of aggregate "carrier" errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter must be equivalent to:
 *
 *    - 30.3.1.1.13 aCarrierSenseErrors
 *
 * @tx_fifo_errors: Number of frame transmission errors due to device
 *   FIFO underrun / underflow. This condition occurs when the device
 *   begins transmission of a frame but is unable to deliver the
 *   entire frame to the transmitter in time for transmission.
 *   Part of aggregate "carrier" errors in `/proc/net/dev`.
 *
 * @tx_heartbeat_errors: Number of Heartbeat / SQE Test errors for
 *   old half-duplex Ethernet.
 *   Part of aggregate "carrier" errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices possibly equivalent to:
 *
 *    - 30.3.2.1.4 aSQETestErrors
 *
 * @tx_window_errors: Number of frame transmission errors due
 *   to late collisions (for Ethernet - after the first 64B of transmission).
 *   Part of aggregate "carrier" errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter must be equivalent to:
 *
 *    - 30.3.1.1.10 aLateCollisions
 *
 * @rx_compressed: Number of correctly received compressed packets.
 *   This counters is only meaningful for interfaces which support
 *   packet compression (e.g. CSLIP, PPP).
 *
 * @tx_compressed: Number of transmitted compressed packets.
 *   This counters is only meaningful for interfaces which support
 *   packet compression (e.g. CSLIP, PPP).
 *
 * @rx_nohandler: Number of packets received on the interface
 *   but dropped by the networking stack because the device is
 *   not designated to receive packets (e.g. backup link in a bond).
 *
 * @rx_otherhost_dropped: Number of packets dropped due to mismatch
 *   in destination MAC address.

/**
 * DOC: Bridge enum definition
 *
 * Please *note* that the timer values in the following section are expected
 * in clock_t format, which is seconds multiplied by USER_HZ (generally
 * defined as 100).

 *   The group forwarding mask. This is the bitmask that is applied to
 *   decide whether to forward incoming frames destined to link-local
 *   addresses (of the form 01:80:C2:00:00:0X).
 *
 *   The default value is 0, which means the bridge does not forward any
 *   link-local frames coming on this port.

 *
 * @IFLA_BR_VLAN_DEFAULT_PVID
 *   VLAN ID applied to untagged and priority-tagged incoming packets.
 *
 *   The default value is 1. Setting to the special value 0 makes all ports of

 */
enum {

};

/**
 * DOC: Bridge port enum definition
 *
 * @IFLA_BRPORT_STATE
 *   The operation state of the port. Here are the valid values.
 *
 *     * 0 - port is in STP *DISABLED* state. Make this port completely
 *       inactive for STP. This is also called BPDU filter and could be used
 *       to disable STP on an untrusted port, like a leaf virtual device.
 *       The traffic forwarding is also stopped on this port.
 *     * 1 - port is in STP *LISTENING* state. Only valid if STP is enabled
 *       on the bridge. In this state the port listens for STP BPDUs and
 *       drops all other traffic frames.
 *     * 2 - port is in STP *LEARNING* state. Only valid if STP is enabled on
 *       the bridge. In this state the port will accept traffic only for the
 *       purpose of updating MAC address tables.
 *     * 3 - port is in STP *FORWARDING* state. Port is fully active.
 *     * 4 - port is in STP *BLOCKING* state. Only valid if STP is enabled on
 *       the bridge. This state is used during the STP election process.
 *       In this state, port will only process STP BPDUs.
 *
 * @IFLA_BRPORT_PRIORITY
 *   The STP port priority. The valid values are between 0 and 255.
 *
 * @IFLA_BRPORT_COST
 *   The STP path cost of the port. The valid values are between 1 and 65535.
 *
 * @IFLA_BRPORT_MODE
 *   Set the bridge port mode. See *BRIDGE_MODE_HAIRPIN* for more details.
 *
 * @IFLA_BRPORT_GUARD
 *   Controls whether STP BPDUs will be processed by the bridge port. By
 *   default, the flag is turned off to allow BPDU processing. Turning this
 *   flag on will disable the bridge port if a STP BPDU packet is received.
 *
 *   If the bridge has Spanning Tree enabled, hostile devices on the network
 *   may send BPDU on a port and cause network failure. Setting *guard on*
 *   will detect and stop this by disabling the port. The port will be
 *   restarted if the link is brought down, or removed and reattached.
 *
 * @IFLA_BRPORT_PROTECT
 *   Controls whether a given port is allowed to become a root port or not.
 *   Only used when STP is enabled on the bridge. By default the flag is off.
 *
 *   This feature is also called root port guard. If BPDU is received from a
 *   leaf (edge) port, it should not be elected as root port. This could
 *   be used if using STP on a bridge and the downstream bridges are not fully
 *   trusted; this prevents a hostile guest from rerouting traffic.
 *
 * @IFLA_BRPORT_FAST_LEAVE
 *   This flag allows the bridge to immediately stop multicast traffic
 *   forwarding on a port that receives an IGMP Leave message. It is only used
 *   when IGMP snooping is enabled on the bridge. By default the flag is off.
 *
 * @IFLA_BRPORT_LEARNING
 *   Controls whether a given port will learn *source* MAC addresses from
 *   received traffic or not. Also controls whether dynamic FDB entries
 *   (which can also be added by software) will be refreshed by incoming
 *   traffic. By default this flag is on.
 *
 * @IFLA_BRPORT_UNICAST_FLOOD
 *   Controls whether unicast traffic for which there is no FDB entry will
 *   be flooded towards this port. By default this flag is on.
 *
 * @IFLA_BRPORT_PROXYARP
 *   Enable proxy ARP on this port.
 *
 * @IFLA_BRPORT_LEARNING_SYNC
 *   Controls whether a given port will sync MAC addresses learned on device
 *   port to bridge FDB.
 *
 * @IFLA_BRPORT_PROXYARP_WIFI
 *   Enable proxy ARP on this port which meets extended requirements by
 *   IEEE 802.11 and Hotspot 2.0 specifications.
 *
 * @IFLA_BRPORT_ROOT_ID
 *
 * @IFLA_BRPORT_BRIDGE_ID
 *
 * @IFLA_BRPORT_DESIGNATED_PORT
 *
 * @IFLA_BRPORT_DESIGNATED_COST

 * @IFLA_BRPORT_CONFIG_PENDING
 *
 * @IFLA_BRPORT_MESSAGE_AGE_TIMER
 *
 * @IFLA_BRPORT_FORWARD_DELAY_TIMER
 *
 * @IFLA_BRPORT_HOLD_TIMER
 *
 * @IFLA_BRPORT_FLUSH
 *   Flush bridge ports' fdb dynamic entries.
 *
 * @IFLA_BRPORT_MULTICAST_ROUTER
 *   Configure the port's multicast router presence. A port with
 *   a multicast router will receive all multicast traffic.
 *   The valid values are:
 *
 *     * 0 disable multicast routers on this port
 *     * 1 let the system detect the presence of routers (default)
 *     * 2 permanently enable multicast traffic forwarding on this port
 *     * 3 enable multicast routers temporarily on this port, not depending
 *         on incoming queries.
 *
 * @IFLA_BRPORT_PAD
 *
 * @IFLA_BRPORT_MCAST_FLOOD
 *   Controls whether a given port will flood multicast traffic for which
 *   there is no MDB entry. By default this flag is on.
 *
 * @IFLA_BRPORT_MCAST_TO_UCAST
 *   Controls whether a given port will replicate packets using unicast
 *   instead of multicast. By default this flag is off.
 *
 *   This is done by copying the packet per host and changing the multicast
 *   destination MAC to a unicast one accordingly.
 *
 *   *mcast_to_unicast* works on top of the multicast snooping feature of the
 *   bridge. Which means unicast copies are only delivered to hosts which
 *   are interested in unicast and signaled this via IGMP/MLD reports previously.
 *
 *   This feature is intended for interface types which have a more reliable
 *   and/or efficient way to deliver unicast packets than broadcast ones
 *   (e.g. WiFi).
 *
 *   However, it should only be enabled on interfaces where no IGMPv2/MLDv1
 *   report suppression takes place. IGMP/MLD report suppression issue is
 *   usually overcome by the network daemon (supplicant) enabling AP isolation
 *   and by that separating all STAs.
 *
 *   Delivery of STA-to-STA IP multicast is made possible again by enabling
 *   and utilizing the bridge hairpin mode, which considers the incoming port
 *   as a potential outgoing port, too (see *BRIDGE_MODE_HAIRPIN* option).
 *   Hairpin mode is performed after multicast snooping, therefore leading
 *   to only deliver reports to STAs running a multicast router.
 *
 * @IFLA_BRPORT_VLAN_TUNNEL
 *   Controls whether vlan to tunnel mapping is enabled on the port.
 *   By default this flag is off.
 *
 * @IFLA_BRPORT_BCAST_FLOOD
 *   Controls flooding of broadcast traffic on the given port. By default
 *   this flag is on.
 *
 * @IFLA_BRPORT_GROUP_FWD_MASK
 *   Set the group forward mask. This is a bitmask that is applied to
 *   decide whether to forward incoming frames destined to link-local
 *   addresses. The addresses of the form are 01:80:C2:00:00:0X (defaults
 *   to 0, which means the bridge does not forward any link-local frames
 *   coming on this port).
 *
 * @IFLA_BRPORT_NEIGH_SUPPRESS
 *   Controls whether neighbor discovery (arp and nd) proxy and suppression
 *   is enabled on the port. By default this flag is off.
 *
 * @IFLA_BRPORT_ISOLATED
 *   Controls whether a given port will be isolated, which means it will be
 *   able to communicate with non-isolated ports only. By default this
 *   flag is off.
 *
 * @IFLA_BRPORT_BACKUP_PORT
 *   Set a backup port. If the port loses carrier all traffic will be
 *   redirected to the configured backup port. Set the value to 0 to disable
 *   it.
 *
 * @IFLA_BRPORT_MRP_RING_OPEN
 *
 * @IFLA_BRPORT_MRP_IN_OPEN
 *
 * @IFLA_BRPORT_MCAST_EHT_HOSTS_LIMIT
 *   The number of per-port EHT hosts limit. The default value is 512.
 *   Setting to 0 is not allowed.
 *
 * @IFLA_BRPORT_MCAST_EHT_HOSTS_CNT
 *   The current number of tracked hosts, read only.
 *
 * @IFLA_BRPORT_LOCKED
 *   Controls whether a port will be locked, meaning that hosts behind the
 *   port will not be able to communicate through the port unless an FDB
 *   entry with the unit's MAC address is in the FDB. The common use case is
 *   that hosts are allowed access through authentication with the IEEE 802.1X
 *   protocol or based on whitelists. By default this flag is off.
 *
 *   Please note that secure 802.1X deployments should always use the
 *   *BR_BOOLOPT_NO_LL_LEARN* flag, to not permit the bridge to populate its
 *   FDB based on link-local (EAPOL) traffic received on the port.
 *
 * @IFLA_BRPORT_MAB
 *   Controls whether a port will use MAC Authentication Bypass (MAB), a
 *   technique through which select MAC addresses may be allowed on a locked
 *   port, without using 802.1X authentication. Packets with an unknown source
 *   MAC address generates a "locked" FDB entry on the incoming bridge port.
 *   The common use case is for user space to react to these bridge FDB
 *   notifications and optionally replace the locked FDB entry with a normal
 *   one, allowing traffic to pass for whitelisted MAC addresses.
 *
 *   Setting this flag also requires *IFLA_BRPORT_LOCKED* and
 *   *IFLA_BRPORT_LEARNING*. *IFLA_BRPORT_LOCKED* ensures that unauthorized
 *   data packets are dropped, and *IFLA_BRPORT_LEARNING* allows the dynamic
 *   FDB entries installed by user space (as replacements for the locked FDB
 *   entries) to be refreshed and/or aged out.
 *
 * @IFLA_BRPORT_MCAST_N_GROUPS
 *
 * @IFLA_BRPORT_MCAST_MAX_GROUPS
 *   Sets the maximum number of MDB entries that can be registered for a
 *   given port. Attempts to register more MDB entries at the port than this
 *   limit allows will be rejected, whether they are done through netlink
 *   (e.g. the bridge tool), or IGMP or MLD membership reports. Setting a
 *   limit of 0 disables the limit. The default value is 0.
 *
 * @IFLA_BRPORT_NEIGH_VLAN_SUPPRESS
 *   Controls whether neighbor discovery (arp and nd) proxy and suppression is
 *   enabled for a given port. By default this flag is off.
 *
 *   Note that this option only takes effect when *IFLA_BRPORT_NEIGH_SUPPRESS*
 *   is enabled for a given port.
 *
 * @IFLA_BRPORT_BACKUP_NHID
 *   The FDB nexthop object ID to attach to packets being redirected to a
 *   backup port that has VLAN tunnel mapping enabled (via the
 *   *IFLA_BRPORT_VLAN_TUNNEL* option). Setting a value of 0 (default) has
 *   the effect of not attaching any ID.
