2010-11-22ath9k_htc: fix eeprom accessFelix Fietkau
wireless-testing commit a05b5d45049d60a06a1b12976150572304a51928 ath9k: add support for reading eeprom from platform data on PCI devices This change moved the initialization of the AH_USE_EEPROM flag from ath9k_hw to ath9k.

2010-11-22ath9k: fix timeout on stopping rx dmaFelix Fietkau
It seems that using ath9k_hw_stoppcurecv to stop rx dma is not enough. When it's time to stop DMA, the PCU is still busy, so the rx enable bit never clears. Using ath9k_hw_abortpcurecv helps with getting rx stopped much faster, with this change, I cannot reproduce the rx stop related WARN_ON anymore.

2010-11-18ath9k_hw: support reading calibration data from flash on AR9003Felix Fietkau

2010-11-17ath9k_hw: add support for reading EEPROM data from the internal OTP ROMFelix Fietkau
Some of the new AR9003 cards do not come with an external EEPROM chip anymore. Calibration data on these cards is stored in the OTP ROM on the chip. This patch adds support for reading this data, and also adds support for different EEPROM chip sizes (512 bytes instead of 1K). Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-17ath9k: store frame information used by aggregation inside the skb tx infoFelix Fietkau
Since the pointers after the rates in the tx info cannot be used anymore after frames have been queued, this area can be used to store information that was previously stored in the ath_buf. With these changes, we can delay the ath_buf assignment in the aggregation code until aggregates are formed. That will not only make it possible to simplify DMA descriptor setup to do less rewriting of uncached memory, but will also make it easier to move aggregation out of the core of the ath9k tx path.
