Hello,
I hope my netgraph (understanding) issue/question fits to net@.
My issue:
I'm observing VLAN tagged frames reading VID=0 when received inside a
bhyve(8) VM, while they (correctly) read VID=77 at ng_eiface(4)
ng_bridge(4) members.
Narrowed down to be a netgraph(4) problem:
Using if_tap(4) as bhyve(8) backend instead of netgraph preserves VLAN
tagging (tcpdump inside the otherwise same VM reads VID-77).
Blocks use case:
Having a VM with a 'trunk' port.
If anybody has an idea or is interested in some more details, please
have a look at https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285755
Thanks in advance,
-harry
