[ovs-dev] [PATCH v2] tnl-ports: Add destination IP and MAC address to the match.
Pravin B Shelar

Thu Sep 3 07:42:34 UTC 2015
Currently tnl-port table wildcard destination ip and mac addresses
for given tunnel packet. That could result accepting tunnel
packets destined for other hosts. Following patch adds
support for matching for ip and mac address.
IP address upates to tnl-port table are piggybacked on
ovs-router updates.

tnl-port table does not depends on /32 route.
