The XB113 cards are single band, 5 GHz-only, but the default settings were configured to assume it was dual band. Users of these cards then would see 2.4 GHz channels but you would never get any scan results from these channels given that the radio is not present.

With AR9003 at about ~ 10 feet from an AP that uses RTS / CTS you will be able to associate but not not get data through given that the power for the rates used was set too low. This increases the power and permits data connectivity at longer distances from access points when connected with HT40. Without this you will not get any data through when associated to APs configured in HT40 at about more than 10 feet away.

The commit 'ath9k_hw: Disable PAPRD for rates with low Tx power' changed the code that sets the PAPRD rate masks to use only either the HT20 mask or the HT40 mask. This is wrong, as the hardware can still use HT20 rates even when configured for HT40, and the operating channel mode does not affect PAPRD operation. The register for the HT40 rate mask is applied as a mask on top of the other registers to selectively disable PAPRD for specific rates on HT40 packets only. This patch changes the code back to the old behavior which matches the intended use of these registers. While with current cards this should not make any practical difference (according to Atheros, the HT20 and HT40 mask should always be equal), it is more correct that way, and maybe the HT40 mask will be used for some rare corner cases in the future.

The EEPROM contains scale factors for the tx power, which define the range of allowable difference between target power and training power. If the difference is too big, PA predistortion cannot be used. For 2.4 GHz there is only one scale factor, for 5 GHz there are three, depending on the specific frequency range.

AR9280 based hardware with 3 antennas and slow antenna diversity has not been seen in the wild and ath9k does not support that form of antenna diversity, so remove the EEPROM ops for it.

Parsing data using bitfields is messy, because it makes endian handling much harder. AR9002 and earlier got it right, AR9003 got it wrong. This might lead to either using too high or too low tx power values, depending on frequency and eeprom settings. Fix it by getting rid of the CTL related bitfields entirely and use masks instead.

This feature is to mitigate the problem of certain 3 stream chips that exceed the PCIe power requirements.An EEPROM flag controls which chips have APM enabled which is basically read from miscellaneous configuration element of the EEPROM header. This workaround will reduce power consumption by using 2 Tx chains for Single and Double stream rates (5 GHz only).All self generated frames (regardless of rate) are sent on 2 chains when this feature is enabled(Chip Limitation).
