svn version r2992
I have checked it on various systems ( from Pentium M to pentium D ) and
different cards. The Dmesg is also flooded with "ath_mgtstart: discard, no
xmit buf" message.
I guess some one tempered with txq queue and left some thing broken.
I have switched back to the stable revision as packets are sent
successfully even when fragmented.
Let me know if you need further information.
The AP and stations all use the same version of driver (r2992).

Please verify if latest trunk still suffers from this problem.
