Subject[34-longterm 054/247] p54: fix sequence no. accounting off-by-one error
Date
From: Christian Lamparter <chunkeey@googlemail.com>

-------------------
This is a commit scheduled for the next v2.6.34 longterm release.
If you see a problem with using this for longterm, please comment.
-------------------

commit 3b5c5827d1f80ad8ae844a8b1183f59ddb90fe25 upstream.

P54_HDR_FLAG_DATA_OUT_SEQNR is meant to tell the
firmware that "the frame's sequence number has
already been set by the application."

Whereas IEEE80211_TX_CTL_ASSIGN_SEQ is set for
frames which lack a valid sequence number and
either the driver or firmware has to assign one.

Yup, it's the exact opposite!
