Synopsis: Vlan hwtagging on fxp under 7.4-PRERELEASE doesn't work State-Changed-From-To: open->feedback State-Changed-By: yongari State-Changed-When: Tue Mar 1 18:16:26 UTC 2011 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?
