While debugging a problem with group-rekeys, we noticed that the sniffer (on external machine)

It seems to me that these should be in the VO queue instead, or at least
we should be able to specify the queue in supplicant when sending the frames?
Hrmm, actually it appears the mac80211 layer tries to send on VO. Maybe
some of my hackings are messing this up...I'll go dig deeper.
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
