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. --=20 You are receiving this mail because: You are the assignee for the bug.=
