Miller 1216266649 -0700 core: add stat to track unresolved discards in neighbor cache in __neigh_event_send, if we have a neighbour entry which is in NUD_INCOMPLETE state, we enqueue any outbound frames to that neighbour to the neighbours arp_queue, which is default capped to a length of 3 skbs. If that queue exceeds its set length, it will drop an skb on the queue to enqueue the newly arrived skb. This results in a drop for which we have no statistics incremented. This patch adds an unresolved_discards stat to /proc/net/stat/ndisc_cache to track these lost frames. Signed-off-by: Neil Horman Signed-off-by: David S. Miller ޥ-.
