[101/145] ath5k: use correct packet type when transmitting

[Greg KH]

2.6.32-stable review patch.  If anyone has any objections, please let me know.

----------------
From: Bob Copeland <me@xxxxxxxxxxxxxxx>

commit 2ac2927a953a01c83df255118922cce1523d1a18 upstream.

The hardware needs to know what type of frames are being
sent in order to fill in various fields, for example the
timestamp in probe responses (before this patch, it was
always 0).  Set it correctly when initializing the TX
descriptor.
