--- Comment #2 from Peter Grehan <grehan at 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 only
if LRO is enabled on an interface, which I think should not be the case from
the bridge addition above.
