Subject: [PATCH net 0/2] ipvlan: make addrs_lock be per port

It seems that initial code of the ipvlan was written in the assumption
that all addr-change occurs under rtnl-lock. But it's not true
for the IPv6 case.

Make addrs_lock be per port and fix possible races.

Note: the race is very rare and unlikely to occur in real environment.

Dmitry Skorodumov (2):
  ipvlan: Make the addrs_lock be per port
  ipvlan: Take addr_lock in ipvlan_open()
