That affects another driver and I assume I cannot directly use this
patch.
I tried to remove vlangwfilter, this changed the interface, but the
issue persists. Enabling promisc fixes it, so I assume the issue is at
a different place.
[m@test ~]$ ifconfig vtnet0 |grep --color -i vlan
options=ed07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6,HWSTATS>
[m@test ~]$ sudo ifconfig vtnet0 -vlanhwfilter
[m@test ~]$ ifconfig vtnet0 |grep --color -i vlan
options=ec07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6,HWSTATS>
I will also ask on the virtualbox list if the virtio interface supports
VLAN filtering.
