Thanks Chris.  One issue is that OVS can potentially be used to do
more than just straight bridging.  If you imagine it being used as a
bump in the wire to do filtering, for example, then it should still be
OK to use with wireless devices.  Over time, we've either relaxed or
moved to userspace similar checks in order to provide maximum
flexibility - i.e. disabling LRO is something that we're now doing in
userspace because it's not always strictly necessary and userspace has
more information.  Can you think of a way to do something similar
here?
