[ovs-dev] [PATCH 3/3] xlate: call tnl_neigh_snoop() from terminate_native_tunnel()
Zoltan Balogh
zoltan.balogh at ericsson.com
Tue Dec 5 10:43:16 UTC 2017
Move tunnel neigh snooping from do_xlate_actions() to
terminate_native_tunnel() in order to keep ARP neighbor cache clean.
Furthermore filter ARP reply and Neighbor Advertisement messages
addressing tunnel endpoint.
