* ath5k_hw_noise_floor_calibration - perform PHY noise floor calibration
*
* @ah: struct ath5k_hw pointer we are operating on
* @freq: the channel frequency, just used for error logging
*
* This function performs a noise floor calibration of the PHY and waits for
* it to complete. Then the noise floor value is compared to some maximum
* noise floor we consider valid.
*
* Note that this is different from what the madwifi HAL does: it reads the
* noise floor and afterwards initiates the calibration. Since the noise floor
* calibration can take some time to finish, depending on the current channel
* use, that avoids the occasional timeout warnings we are seeing now.
*
* See the following link for an Atheros patent on noise floor calibration:
* http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL \
* &p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=7245893.PN.&OS=PN/7
*
* XXX: Since during noise floor calibration antennas are detached according to
* the patent, we should stop tx queues here.
