2013-09-26ath9k: Fix issue with parsing malformed CFP IESujith Manoharan
All QCA chips have the ability to parse the CF Parameter Set IE in beacons. If the IE is malformed in the beacons from some APs [1], the HW locks up. In AP mode, a beacon stuck would happen and in client mode, a disconnection usually is the result. To fix this issue, set the AR_PCU_MISC_MODE2_CFP_IGNORE to ignore the CFP IE in beacons - this is applicable for all chips. For AP mode, if this issue happens, the NAV is also corrupted and has to be reset - this will be done in a subsequent patch.

2013-09-26ath9k: Fix calibration for AR9462Sujith Manoharan
TX IQ calibration is disabled by default for AR9462, this is done using the initvals (reg 0xa644). But, to compensate for this, the AR_PHY_RX_DELAY register should be set to the max allowed value when performing calibration.

2013-09-26ath9k: replace snprintf() with scnprintf()Zefir Kurtisi
Whenever the return value of snprintf() is used to calculate remaining buffer-space, we wanted to use sncprintf() instead. Indentation is adapted where possible. Some lines exceed the line width limit, either they did it already before, or since they can not be broken reasonably well.

2013-09-03ath10k: check chip id from the soc register during probeKalle Valo
ath10k doesn't support qca988x hw1.0 boards anymore. Unfortunately the PCI id is the same in hw1.0 and hw2.0 so ath10k tries to use hw1.0 boards anyway. But without hw1.0 workarounds in place ath10k just crashes horribly. To avoid using hw1.0 boards at all add a chip id detection and fail the probe if hw1.0 is detected: [ 5265.786408] ath10k: ERROR: qca988x hw1.0 is not supported [ 5265.786497] ath10k: Unsupported chip id 0x043200ff [ 5265.786574] ath10k: could not register driver core (-95) [ 5265.793191] ath10k_pci: probe of 0000:02:00.0 failed with error -95 Also add a warning if there's an unknown chip id but continue the boot process normally anyway.
