   I've just updated to FreeBSD 8.1 PRERELEASE and I see the
unsupported rate problem again. I applied the patch for CURRENT and it
works. So I guess the patch was not MFC in the 8.1 branch.

   However it still works slow (betwenn 200 and 300 kbytes/s). I tried
using a rum dongle with the same AP (which is a 8.0-STABLE system with
an Atheros card) and works great when uploading (2Mb sustained).

   In my laptop I see now messages like these :

            bwn0: RX decryption attempted (old 0 keyidx 0x1)

   If you want me to try anything, let me know.

   Regards,

   Gus
