* wl1271: Change wl12xx Files NamesShahar Levi2010-11-2233-151/+154
| | | | | | | | | All files name prefix removed due to the fact that wl12xx driver supports wl1271 and wl1273. Also the definition in Kconfig and header files changed respectively. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>
* ath9k_hw: support reading calibration data from flash on AR9003Felix Fietkau2010-11-181-0/+15
| | | | | | | | | Embedded boards do not have compressed EEPROM data, they use the struct ar9003_eeprom layout, with little endian fields, so copying the raw data to the eeprom buffer is enough. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath9k_hw: add support for reading EEPROM data from the internal OTP ROMFelix Fietkau2010-11-172-6/+93
| | | | | | | | | | | 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.

* ath9k: store frame information used by aggregation inside the skb tx infoFelix Fietkau2010-11-172-109/+109
| | | | | | | | | | | | | | 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.

* rt2x00: Fix rt2800 USB TX Path DMA issueRA-Jay Hung2010-11-171-13/+26
| | | | | | | | | | | | | | | rt2800usb chips need to add 1~3 bytes zero padding after each 802.11 header & payload, and at the end need to add 4 bytes zero padding whether doing TX bulk aggregation or not, TXINFO_W0_USB_DMA_TX_PKT_LEN in TXINFO must include 1-3 bytes padding after 802.11 header & payload but do not include 4 bytes end zero padding. In rt2800usb_get_tx_data_len do not consider multiple of the USB packet size case, sometimes this will cause USB DMA problem.
