Log Message:
e1000 VLAN offload emulation (Alex Williamson)

We're currently ignoring the e1000 VLAN tagging, stripping and filtering
features in the e1000 emulation.  This patch adds backing for the
relevant registers and provides a software implementation of the
acceleration, such that a guest can make use of VLANs.

This is mostly (only?) useful for a guest on a bridge (not user mode
networking).  The only caveat beyond that is that you need to make sure
the host NIC isn't doing it's own tagging, stripping, or filtering.
This generally means the host NIC on the bridge should not be part of a
VLAN.
