--- Comment #19 from Vincenzo Maffione <vmaffi...@freebsd.org> ---
If I'm not mistaken if_vtnet with jumbo frames should work even if the host
does not support rx mergeable buffers... if that doesn't work I would be
inclined to think that this particular situation is not supported by the driver
(IOW 64KB packets are not handled). Can somebody test it again with the
stable/11 code?
And yes, currently rx mergeable buffers are advertised by the host only when
the vale net backend is used (for both if_vtnet and e1000).
However, now that I think about that, rx mergeable buffers is not something
that actually depends on the net backend, so if we advertise them in any case
(e.g., also with the tap backend), things should magically work. I'll test this
theory in the next days.
