Alex, I don't see rx-vlan-offload option in my ethtool. strange, maybe it is not available in all ethtool versions ?

I'm accessing the ethernet header, and it always gives me non extended ethernet header (without vlan information). I can see the vlan tag in vlan_tci field in sk_buff, but this is not exactly what I need, I need the header AS-IS with the original (extended) ethernet header. Thanks.
