Let me do some more digging. If you set the channel like that you run
through a different code path to if you do it via scanning.
Also, I did tidy up and remove some code before I posted that diff.
Maybe some of it was needed.

.. hey, scratch that. 11n aggregation works in IBSS mode with my
patch, at least on ath(4).
I bet there's all kinds of weird subtle crap going on that we need to
fix, but the basics are working.

Here's what I have trimmed this down to so far:
http://people.freebsd.org/~adrian/ath/20121212-11n-ibss-and-other-stuff-3.diff
Please disable ampdu for now (ifconfig wlanX -ampdu) as it just plain
doesn't work.
I'll figure out why once I figure out the cleanest way to get this 11n
IBSS stuff work
Hm, you may be right; but I disabled HT protection entirely and stuck
it on a very quiet channel.
It's possible both ends were colliding with each other though.
I did add some HT update code to the adhoc beacon processing, though.
It's just not entirely clear how to handle that given the nature o

.. so now I have 11n IBSS working, but the performance is pretty
shocking. I bet there's some timers that are just not programmed
correctly.
I see massive numbers of long retries and CRC errors.
In any case, there are a few odd things out:
* ieee80211_ies_expand() doesn't parse HTINFO, only HTCAP
Ok, wow. I think I finally understand the level of "huh?" going on here.
When a new BSS is created, everything now works out great. It creates
a BSS, the channel is promoted to 11n correctly, it gets the 11n IE's
populated, etc.
When you're joining a BSS however, it doesn't do any of this.
adhoc_
Ok, I've started digging into this a bit more. I need to get 11n adhoc
working so I can get 11n ahdemo working, so we can actually do 11n
TDMA at some point in the near future.
There's a whole lot of missing stuff:
* ieee80211_add_neighbor() and ieee80211_init_neighbor() don't know
about HT at al
Ok,
Please reply to the PR with some debugging output.
On both nodes, enable this:
wlandebug -i wlanX +assoc +ht +rate
Then do some pings on either side. Don't do iperf, it'll dump out way
too much debugging (one line per frame.) Just pings and record both
sides is enough.
It'll tell me how th

.. please file a bug. :-) Now that I have VIMAGE mostly working with
wifi, I'd like to take the opportunity to fix whatever 11n ibss bugs
you see.
There's no reason why aggregation and MCS rates shouldn't work with
IBSS. The only questionable issue right now is encryption and that
requires some st
Ah, it looks like the MCS rate stuff isn't being setup or negotiated right?
Please file a bug. I'm not sure if I'll have time to dig into it
though; but it should be easy to fix.

Nope, still the same. (done on both sides)

Hi,
Try disabling ampdu - ifconfig wlanX -ampdu
