/**
 * 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.
