ice: clear port vlan config during reset
Since commit 2a2cb4c6c181 ("ice: replace ice_vf_recreate_vsi() with
ice_vf_reconfig_vsi()") VF VSI is only reconfigured instead of
recreated. The context configuration from previous setting is still the
same. If any of the config needs to be cleared it needs to be cleared
explicitly.
Previously there was assumption that port vlan will be cleared
automatically. Now, when VSI is only reconfigured we have to do it in the
code.
Not clearing port vlan configuration leads to situation when the driver
VSI config is different than the VSI config in HW. Traffic can't be
passed after setting and clearing port vlan, because of invalid VSI
config in HW.
Example reproduction:
> ip a a dev $(VF) $(VF_IP_ADDRESS)
> ip l s dev $(VF) up
> ping $(VF_IP_ADDRESS)
ping is working fine here
> ip link set eth5 vf 0 vlan 100
> ip link set eth5 vf 0 vlan 0
> ping $(VF_IP_ADDRESS)
ping isn't working
Fixes: 2a2cb4c6c181 ("ice: replace ice_vf_recreate_vsi() with ice_vf_reconfig_vsi()")
