--- Comment #3 from Zhenlei Huang <zlei@FreeBSD.org> ---
Can you please test whether the `vlanhwfilter` works without if_bridge(4) ?
That is to say,

```
# ifconfig igb1 vlanhwfilter
# ifconfig igb1.20 create
# ifconfig igb1.20 inet 192.168.20.xxx/24 up
# ping 192.168.20.1

```

Please also be aware that you shall remove the interface igb1 out from bridge
memeber firstly and then do the test.
