Btw, and no need to change anything as far as I'm concerned, but just in
case you weren't familiar with it; that kind of thing might be nicer as
le32_encode_bits(), i.e.

	txwi[6] |= le32_encode_bits(idx, MT_TXD6_TX_RATE);

Personally, I also generally prefer the typed lower-case versions over
FIELD_GET/PREP etc. but YMMV.
