I've dug a bit deeper, but not all the way I guess.

When I sniff on a separate machine, the EAP packets still
show QoS being 'Best Effort' in wireshark.

UDP data packets sent with proper IP TOS show up in
VI or VO as specified.

So, I think this means that either the EAP packets are not actually
going out the VO queue, or they are somehow missing some wifi QoS config
in their header.

I just tested this with the latest wireless-testing tree, totally un-modified.

The sniffer is running my standard set of patches, but I doubt that matters
since it does properly show QoS on UDP packets.

I'll go look to see if I can figure out where the wifi frame TOS bits
are configured..but if someone has suggestions, let me know!

Thanks,
Ben
