Our hardware strips VLAN tags in order to support Data Center Bridging (I think the details are in 802.1Q for DCB). DCB uses the same offset as VLAN tags and if we didn't strip the tags we couldn't have interoperability between endpoints that had DCB enabled and not enabled.

Neither the packet is seen on the ethereal capture. Here we are just using PF-PACKET socket and no IP and Vlan is configured on the physical interface. The same test if we run on 1 G node it works , so as it seems there is some limitations with this 10G driver. Can you please help.
