Hello List,
I am trying to get a 82546G dual NIC Intel card to do bonding with vlans
and a bridge for a xen server. I would like to be able to setup a bridge
and then assign it to a VM(domU) so it is on a specific VLAN.
I have bonded eth0 and eth1 to bond0 and have created a bridge and
assigned the vlan to the bridge. When I try to send data through the
bridge and I am using tcpdump to sniff the wire I cannot see the VLAN
tag in the packet.
I updated the driver to 8.0.30-NAPI because I had read that HW
acceleration on the card with earlier drivers was stripping the VLAN tag
off of the packet. But I am still not seeing the VLAN tag after updating
the driver.
At this point I am lost and am not sure what to try next. Does this card
support VLAN tagging? From everything I have read it does but can
someone who knows for sure confirm that for me please? Is there
something I am not understanding on why I am not seeing the tag? I have
tried to ping, dhcp, ssh and nothing ever shows the VLAN in the packet.
Any help would be greatly appreciated!! :)
