From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

[ Upstream commit c2ef057ee775e229d3138add59f937d93a3a59d8 ]

In case of device reconfiguration the driver may reset the device invisible
for other modules, vlan module in particular. So vlans will not be
removed&created and vlan filters will not be configured in the device.
The patch reapplies the vlan filters at device start.

Fixes: 7975d2aff5afb ("net: aquantia: add support of rx-vlan-filter offload")
