You've got a serious misconception about how vlans work.  The only
hardware support that is required is support for a wire MTU of 1504
bytes so the tag fits on the packet without reducing payload size.  Some
interfaces have support for removing the tag from the packet for you and
indicating the tag out of band, but that's only an optimization.
