https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234550 Peter Grehan <grehan@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |grehan@FreeBSD.org --- Comment #2 from Peter Grehan <grehan@FreeBSD.org> --- Jason, would you be able to post your ifconfig output ? I think it will show LRO enabled on VLAN interfaces, when it should be disabled (and also on the parent VLAN interface) when it's added to a bridge group. The reason that hwvlantag will cause LRO is that stripping the VLAN tag will result in the iflib ethertype check of v4/v6 succeeding. However, this is o= nly if LRO is enabled on an interface, which I think should not be the case from the bridge addition above. --=20 You are receiving this mail because: You are on the CC list for the bug.=
