2011-06-22zd1211rw: only update HW beacon if new beacon differs from currectJussi Kivilinna
Update HW beacon only when needed. This appears to make device work in AP-mode (dtim_period=1) somewhat more stable. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-06-22zd1211rw: fix invalid signal values from deviceJussi Kivilinna
Driver uses IEEE80211_HW_SIGNAL_UNSPEC and so signal values reported to mac80211 should be in range 0..100. Sometimes device return out of range values. These out of range values can then trigger warning in cfg80211_inform_bss_frame. This patch adds checks to enforce range returned from driver to mac80211 be in 0..100 range.

2011-06-22b43: HT-PHY: calibrate radio after switching channelRafał Miłecki
After uploading radio values calibration goes in. In MMIO dump it is: radio_read(0x002b) -> 0x0008 radio_write(0x002b) <- 0x0008 radio_read(0x002e) -> 0x0004 radio_write(0x002e) <- 0x0000 radio_read(0x002e) -> 0x0000 radio_write(0x002e) <- 0x0004 radio_read(0x002b) -> 0x0008 radio_write(0x002b) <- 0x0009 To find masks and sets, MMIO hacks were used to fool closed driver.

2011-06-20ath9k_hw: make sure PAPRD training is properly doneMohammed Shafi Shajakhan
checking the status of PAPRD_AGC2_POWER(Log(ADC_power) measured after last gain-change in dB) field suggests whether the PAPRD is completely/properly done. This is an additional check apart from polling for PAPRD done bit being set. Susinder suggests that the ideal power range value should be 0xf0 to 0xfe. With AR9382 we do have the values in this range. to have a common check for all platforms we take agc2_power should be atleast greater than 0xe0 Cc: susinder@qca.qualcomm.com Cc: senthilb@qca.qualcomm.com Cc: kmuthusa@qca.qualcomm.com Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.
