Re: misc/172955: [ath] 11n does not work in adhoc mode

2012-10-23 Thread Adrian Chadd
Ok- the problem here is that unfortunately the adhoc code doesn't do
any of the HT field parsing or upgrading.

Adding the parsing isn't enough, it still doesn't properly negotiate
HT on both ends, so it doesn't upgrade the rate control.

Also - the WME parameters aren't parsed either, leading to your
observation about performance drops between 7x and 8.x.

 Right, it looks like the adhoc nodes are advertising HTCAP in the
 beacons; however it's not actually treating that node as HT capable.
 
 Something needs to upgrade those nodes to HT.
