2011-05-10ath9k: avoid enabling interrupts while processing rxRajkumar Manoharan4-3/+17
The assumsion is that while processing ath9k tasklet, interrupts were already disabled and it will be enabled at the completion of ath9k tasklet. But whenever TSFOOR is raised, the driver configures the beacon timers after having received a beacon frame from the AP which inturn enables the interrupts.

2011-05-05ath9k_hw: fix power for the HT40 duplicate framesLuis R. Rodriguez1-0/+10
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.

2011-05-05ath9k_hw: do noise floor calibration only on required chainsRajkumar Manoharan1-0/+13
At present the noise floor calibration is processed in supported control and extension chains rather than required chains. Unnccesarily doing nfcal in all supported chains leads to invalid nf readings on extn chains and these invalid values got updated into history buffer. While loading those values from history buffer is moving the chip to deaf state. This issue was observed in AR9002/AR9003 chips while doing associate/dissociate in HT40 mode and interface up/down in iterative manner. After some iterations, the chip was moved to deaf state. Somehow the pci devices are recovered by poll work after chip reset. Raading the nf values in all supported extension chains when the hw is not yet configured in HT40 mode results invalid values.

2011-05-05carl9170: fix allmulticast modeNicolas Cavallari1-1/+1
Currently, the driver only disable multicast filtering when the FIF_ALLMULTI driver flag has been just set (ie, if changed_flags& FIF_ALLMULTI and *new_flags& FIF_ALLMULTI) or else it will reenable multicast filtering. But next time, this condition will be false and multicast filtering will be reenabled, even through FIF_ALLMULTI is still set. This mean that allmulticast only works for less than two minutes in ad-hoc mode. This patch fixes that to disable multicast filtering as long as FIF_ALLMULTI is set.

2011-04-26ath9k_hw: Fix Tx IQ Calibration hang issue in AR9003 chipsRajkumar Manoharan3-235/+140
On AR9003 chips, doing three IQ calibrations will possibly cause chip in stuck state. In noisy environment, chip could receive a packet during the middle of three calibrations and it causes the conflict of HW access and the eventual failure. It also causes IQ calibration outliers which results in poor Tx EVM. The IQ Cal procedure is after resetting the chip, run IQ cal 3 times per each cal cycle and find the two closest readings and average of two. The advantage of running Tx IQ cal more than once is that we can compare calibration results for the same gain setting over multiple iterations. Most of the cases the IQ failures were observed after first pass. For the AR9485 and later chips, Tx IQ Calibration is performed along with AGC cal. But for pre-AR9485 chips, Tx IQ cal HW has to be separated from the rest of calibration HW to avoid chip hang. After all calibrations are done in HW, we can start SW post-processing. By doing this way, we minimize the SW difference among all chips. The order of calibration (run IQ cal before other calibration) is also needed to avoid chip hang for chips before AR9485. This issue was originally observed with AR9382. During the issue kernel log was filled with following message ath: timeout (100000 us) on reg 0xa640: 0x00000001 & 0x00000001 != 0x00000000 ath: timeout (100000 us) on reg 0xa2c4: 0x00158dd9 & 0x00000001 != 0x00000000 ath: Unable to reset channel (2412 MHz), reset status -5 ath: Unable to set channel Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.
