Subject: [PATCH net-next v2 4/4] be2net: re-enable vlan filtering mode asap

From: Kalesh AP <kalesh.purayil@...lex.com>

While adding vlans, when the HW limit of vlan filters is reached, the
driver enables vlan promiscuous mode.
Similarily, while removing vlans, the driver must re-enable HW filtering
as soon as the number of vlan filters is within the HW limit.
