ipvlan: Cache net in ipvlan_process_v4_outbound and ipvlan_process_v6_outbound
Compute net once in ipvlan_process_v4_outbound and ipvlan_process_v6_outbound and store it in a variable so that net does not need to be recomputed next time it is used. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
