Well, that's just a switch configuration - tagged on VLAN n or untagged
on VLAN n.  If they've decided to make the port tagged on VLAN n, then
the server needs to support VLAN tagging as well.  Just because both the
switch and the server need to agree on the VLAN it's on doesn't mean
there are other tagged VLANs on the port.
