Hi! I have a patch against iwn(4):
http://people.freebsd.org/~adrian/ath/20131024-iwn-1-fix-xmit-rate-plcp-linkq.diff This does a few things: * The multi-rate retry ("link quality" stuff) on iwn is a table, and I think I broke it slightly when I implemented 11n rate control. This disables it for now, at least until I / someone implements a replacement table setup and linkq decision. * get rid of the rate index stuff - it was used to decide a few things and it was doing legacy-only rate index lookups. I've just removed it; it's not needed. * Teach the raw transmit path to use the new plcp lookup routine that sets things up. * Correctly implement 11g protection. Right now it was a bit of a hack and it was not correct for 11a or 11n operation. I still get transmit hangs on my 4965 but the "invalid rate" failures have disappeared. But for some odd reason, the transmits completed but weren't being marked as failed. I don't yet know why. I'm also not sure why transmit is hanging; sometimes it looks like DMA stalls somehow. So - maybe this'll help with various 11n issues on iwn(4), maybe it won't. I'm not sure yet. I'm trying to avoid taking ownership of iwn(4) but I rather dislike the occasional 5100/4965 hangs..
