--- Comment #2 from sec@42.org ---
In the meantime I found
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D260468 which seems matc=
h with
my problem.

So from 12.2 to 12.3 hwfiltering seems to have gotten enabled by default &&
can't be disabled anymore.

As a workaround I have created vlan interfaces via
ifconfig $iface.$vlan create

ran that in a loop for all vlans currently in use, and I can see the traffic
again in tcpdump

The change to enable vlan filtering should probably be put somewhat promine=
ntly
in the release notes.

Additionally it would be good if the fix from #260468 could be merged to 12=
.3
:-)
