This patch updates the PCI power save handling code, fixing ASPM hangs and handling device state D3 properly. The WAR register is programmed with the correct values now. Signed-off-by: NSujith <Sujith.Manoharan@atheros.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

* Add a few comments, and move the updation of max_power_level to a helper routine. This is also done by non-4K based chipsets, this will be fixed in a separate patch. * Remove two WARs which are required for old AR5416 chipsets, and are not needed for AR9287. * Fix indentation and make things readable.

Rather than doing a series of RMWs, calculate the value to be written to the register in question and do a single REGWRITE. This improves bringup time. This depends on the analog_shiftreg configuration option, which is currently buggy. For AP mode, a delay of 100us has to be the default. For station mode, this knob has to be enabled on a per-case basis, though it is a little unclear on when to enable a delay. This can be fixed later though.

This patch replaces the buggy 'ath9k: Group Key fix for VAPs' change. For AP mode group keys, use the BSSID as lookup mac address, with the multicast keysearch bit set. For IBSS mode, use the peer's MAC address with multicast keysearch. For STA mode, keep using the group key slots. Signed-off-by: NFelix Fietkau <nbd@openwrt.org> Signed-off-by: NJohn W.

If a MAC address for a key table entry is flagged with the multicast bit (0x01), indicate to the hardware that multicast lookup instead of unicast lookup should be used. The multicast bit itself never makes it to the actual keytable entry register, as it is shifted out. Signed-off-by: NFelix Fietkau <nbd@openwrt.org> Signed-off-by: NJohn W.

We dereference "wmi" on the line before and also when we initialize "ah". This check has always been after a dereference since the first commit a couple months ago. Looking through the code, it looks like "wmi" can't actually be null here so I just removed the check.

The old code logically did not make sense and seems to have been confused by the fact that we could have newer EEPROMs on older hardware. In any case the spur mitigation filter was set if the srev was >= AR5K_SREV_AR5424. Spur info is available only from EEPROM versions bigger than 5.3 but but the EEPOM routines will use static values for older versions, so that should be o.k.

As far as we know, only NF calibration interferes with RX/TX so we can leave the queues enabled for the other calibrations. BTW: Stopping the queues is not enough for avoiding transmissions, since there might be packets in the queue + beacons are also sent regularly! But i leave it like this until we have a better solution (stopping TX DMA?). Signed-off-by: NBruno Randolf <br1@einfach.org> Acked-by: NNick Kossifidis <mickflemm@gmail.com> Signed-off-by: NJohn W.

Seperate noise floor calibration from other PHY calibration and move it to the tasklet. This is the first step to more separation of different calibrations. Also move out ath5k_hw_request_rfgain_probe(ah) so we have one clean function for I/Q calibration on 5111x parts.

The snprintf() function returns the number of bytes that *would* have been written (not counting the NULL terminator) and that can potentally be more than the size of the buffer. In this patch if there were one liners where string clearly fits into the buffer, then I changed snprintf to sprintf(). It's confusing to use the return value of snprintf() as a limitter without verifying that it's smaller than size. This is what initially caught my attention here. If we use the return value of sprintf() instead future code auditors will assume we've verified that it fits already. Also I did find some places where it made sense to use the return value after we've verified that it is smaller than the buffer size. Finally the read_file_rcstat() function added an explicit NULL terminator before calling snprintf(). That's unnecessary because snprintf() will add the null terminator automatically.
