2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------ 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.
