macvlan: receive multicast with local address
When implementing VRRP v2 using macvlan several problems were discovered. VRRP is weird in that all routers participating in a redundant group use the same virtual MAC address. Macvlan is a natural driver to use for this but it doesn't work. The problem is that packets with a macvlan device's source address are not received. The problem is actually a regression that date back almost 2 years now. The original problems started with: commit 618e1b7482f7a8a4c6c6e8ccbe140e4c331df4e9 Author: Arnd Bergmann <arnd@arndb.de> Date: Thu Nov 26 06:07:10 2009 +0000 macvlan: implement bridge, VEPA and private mode This patches restores the original 2.6.32 behavior. Allowing multicast packets received with the VRRP source address to be received. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
