p54: improve TSF timestamp precision
The LMAC API states that the TSF clock value of every rx'ed frame is a "usec accurate timestamp of the hardware clock at the end of frame (before OFDM SIFS EOF padding)". Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
