--- Comment #8 from Alexander Motin <mav@FreeBSD.org> ---
(In reply to Heinz N. Gies from comment #7)
Bridge+epair are the right tools, unless you wish to dedicate one NIC
completely to specific VNET Jail.

I've already told you how to workaround the problem:  when configuring upli=
nk
interface, you can explicitly disable its capabilities that bridge try to
disable otherwise (TSO, LRO, TOE, TXCSUM, TXCSUM6).  In that case bridge sh=
ould
be happy from the beginning and not modify capabilities any more.
