* ath9k_hw: Offload USB eeprom reading to targetSujith Manoharan2011-01-19
| | | | | | | | | For USB devices, reading the EEPROM data can be offloaded to the target. Use multiple register reads to take advantage of this feature to reduce initialization time.

* ath9k_hw: fix endian issues with CTLs on AR9003Felix Fietkau2010-12-02
| | | | | | | | | | | | | 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.

* ath9k_hw: Cleanup TX power calculation for AR9287Sujith2010-06-03
| | | | | | | | | | | | | | * 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.

* ath9k_hw: Optimize ath9k_hw_ar9287_set_board_valuesSujith2010-06-03
| | | | | | | | | | | | | | | 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.

* drivers/net: Remove unnecessary returns from void function()sJoe Perches2010-05-14
| | | | | | | | | | | | | | | | | | | | | | This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand.

* | ath9k: RX stucks during heavy traffic in HT40 mode.Senthil Balasubramanian2009-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running iperf along with p2p traffic on both TX and RX side then stop one side, then stop the other side, then start it up again, eventually the STA gets into a mode that it can not pass data at all. A hardware workaround for invalid RSSI can make FIFO write pointer to jump over read pointer, causing RX data corruption and repeated DMA. Both TX and RX works fine when the workaround is disabled. To replace the original hardware work around, software looks for frames with post delimiter CRC error and mark the RSSI invalid so that the upperlayer will not use the RSSI associated with this frame. So disable the hardware workaround by updating the appropriate registers. Signed-off-by: Senthil Balasubramanian <senthilkumar@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
