Miller 1331964020 -0700 arp: allow arp processing to honor per interface arp_accept sysctl I found recently that the arp_process function which handles all of our received arp frames, is using IPV4_DEVCONF_ALL macro to check the state of the arp_process flag. This seems wrong, as it implies that either none or all of the network interfaces accept gratuitous arps. This patch corrects that, allowing per-interface arp_accept configuration to deviate from the all setting. Note this also brings us into line with the way the arp_filter setting is handled during arp_process execution. Tested this myself on my home network, and confirmed it works as expected.
