From what I have read until now, it seems to be a known problem, and my experience shows that it is still an issue with FreeBSD 11, so I would like to know if it is because tap/bridging a lagg is not a reasonable thing to do anyway…

I have multiple machines on which 2 or more nics make up a LACP lagg
with vlans on it. Those vlan interfaces are in bridges together with the
tap interfaces that are in use by bhyve vms.

Works as long as I "up" the nics in a specific fasion ( " -tso4 -lro
-vlanhwtag " ) . This works on 10.3 and 11.0 as far as I'm aware and I
have never experienced problems with it (Intel / AMD / em driver / bce
driver, re driver , all kinds of combinations).

I have no experience in comparable setups without the vlan "layer" though.

What seems to be your predicament?

Regards,

Ruben
