Subject[PATCH AUTOSEL 4.18 55/59] net: aquantia: fixed enable unicast on 32 macvlan
Date
From: Igor Russkikh <Igor.Russkikh@aquantia.com>

[ Upstream commit bfaa9f8553d5c20703781e63f4fc8cb4792f18fd ]

Fixed a condition mistake due to which macvlans unicast
item number 32 was not added in the unicast filter.

The consequence is that when exactly 32 macvlans are created
on NIC, the last created macvlan receives no traffic because
its MAC was not registered in HW.

Fixes: 94b3b542303f ("net: aquantia: vlan unicast address list correct handling")
