Subject: rt2x00: use correct headroom for transmission
From: Pavel Roskin <[email protected]>
commit b59a52f12e483b79e7d32da7ec30dcf3b2e0210b upstream.
Use rt2x00dev->ops->extra_tx_headroom, not rt2x00dev->hw->extra_tx_headroom
in the tx code, as the later may include other headroom not to be used in
the chipset driver.
