The Adhoc support wasn't parsing and handling the ath specific and WME
IEs, thus the atheros vendor support and WME TXOP parameters aren't being
copied from the peer.
It copies the WME parameters from whichever adhoc node it decides to
associate to, rather than just having them be statically configured
per adhoc node. This may or may not be exactly "right", but it's certainly
going to be more convienent for people - they just have to ensure their
adhoc nodes are setup with correct WME parameters.
Since WME parameters aren't per-node but are configured on hardware TX
queues, if some nodes support WME and some don't - or perhaps, have
different WME parameters - things will get quite quirky.
So ensure that you configure your adhoc nodes with the same WME
parameters.
Secondly - the Atheros Vendor IE is parsed and operated on per-node, so
this should work out ok between nodes that do and don't do Atheros
extensions. Once you see a becaon from that node and you setup the
association state, it _should_ parse things correctly.
TODO:
* I do need to ensure that both adhoc setup paths are correctly updating
the IE stuff. Ie, if the adhoc node is created by a data frame instead
of a beacon frame, it'll come up with no WME/ath IE config. The next
beacon frame that it receives from that node will update the state.
I just need to sit down and better understand how that's suppose to
work in IBSS mode.
Tested:
* AR5416 <-> AR9280 - fast frames and the WME configuration both popped
up. (This is with a local HAL patch that enables the fast frames
capability on the AR5416 chipsets.)

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral). Also there
no longer are separate wlan_scan* modules; this functionality is now
bundled into the wlan module.
