State-Changed-Why: 
I'm pretty sure TSO and VLAN hardware tagging worked without
problems when I firstly implemented that hardware features. AFAIK
FreeBSD is the only OS that takes advantage of these features and
Intel's public data sheet does not (intentionally) mention VLAN
hardware tag insertion/strip feature of controller. The TSO and
VLAN hardware tagging is supported on i82550 and i82551
controllers.

>From your description of the issue and tcpdump output I don't see
any problems. For instance, I see ping for 192.168.3.1 worked and I
also see VLAN encapsulation(ether type 0x8100) header in the
tcpdump. If VLAN hardware tagging does not work, you wouldn't get
any response from 192.168.30.1. So what is your problem?
