I disagree.  Many low costs devices are non-SG still,
there is no reason to penalize them explicitly.

I think instead we should look at ways to propagate
the hardware device features to the bridge.  Even if
a bridge is composed of multiple devices, we just
advertise the subset of features actually supported.
