Interesting, yesterday i run into the same full connection and no data
trouble with the 3.11 mainline kernel.

I played arround a bit with some settings in the openwrt firmware. I
forced ht-mode to 40Mhz even if the second channel was used by another
AP. And all the above messages where gone. Only these sometimes which
should be normal where there:

 STA 4c:0b:3a:85:55:3a WPA: pairwise key handshake completed (RSN)
 STA d0:df:9a:46:3b:c9 WPA: pairwise key handshake completed (RSN)

However, today i can't reproduce it, the settings in openwrt didn't
change and there are tons of messages like above again.

But eventually it points to a direction whats going wrong. Maybe it has
something todo with the channel handling or with which 802.11 standard
the Realtek card sends ACK messages and where the AP is hearing for
them.
