They are ipvlan_process_multicast, ipvlan_rcv_frame, and ipvlan_nf_input. The former two functions already use the ipvlan directly before ipvlan_count_rx, and ipvlan_nf_input gets the ipvlan from ipvl_addr->master, it is not possible to be NULL too. So the ipvlan pointer check is unnecessary in ipvlan_count_rx. Signed-off-by: Gao Feng Signed-off-by: David S.
