2011-01-18iwlwifi: fix valid chain reading from EEPROMWey-Yi Guy1-1/+1
When read valid tx/rx chains from EEPROM, there is a bug to use the tx chain value for both tx and rx, the result of this cause low receive throughput on 1x2 devices becuase rx will only utilize single chain instead of two chains Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

2011-01-18ath9k_hw: do PA offset calibration only on longcal intervalRajkumar Manoharan1-5/+5
The power detector adc offset calibration has to be done on 4 minutes interval (longcal * pa_skip_count). But the commit "ath9k_hw: fix a noise floor calibration related race condition" makes the PA calibration executed more frequently beased on nfcal_pending value. Running PAOffset calibration lesser than longcal interval doesn't help anything and the worse part is that it causes NF load timeouts and RX deaf conditions. In a very noisy environment, where the distance b/w AP & station is ~10 meter and running a downlink udp traffic with frequent background scan causes "Timeout while waiting for nf to load: AR_PHY_AGC_CONTROL=0x40d1a" and moves the chip into deaf state. This issue was originaly reported in Android platform where the network-manager application does bgscan more frequently on AR9271 chips. (AR9285 family usb device).

There is an interoperability with AR9382/AR9380 in L1 state with a few root complexes which can cause a hang. This is fixed by setting some work around bits on the PCIE PHY. We fix by using a new ini array to modify these bits when the radio is idle.

2011-01-10hostap_cs: fix sleeping function called from invalid contextStanislaw Gruszka1-9/+6
pcmcia_request_irq() and pcmcia_enable_device() are intended to be called from process context (first function allocate memory with GFP_KERNEL, second take a mutex). We can not take spin lock and call them. It's safe to move spin lock after pcmcia_enable_device() as we still hold off IRQ until dev->base_addr is 0 and driver will not proceed with interrupts when is not ready.

2011-01-10ipw2200: Check for -1 INTA in tasklet too.Indan Zupancic1-0/+7
This is an attempt to fix a long standing open bug: http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1334 The interrupt handler checks for INTA being -1, apparently that means that the hardware is gone. But the interrupt handler defers actual interrupt processing to a tasklet. By the time the tasklet is run and checks INTA again, the hardware might be gone and INTA be -1, which confuses the driver because all event bits are set. The patch applies to 2.6.37.

By removing two "safety" msleeps (and an echo nop), the channel change delay is effectively halved. Previously, the delay could be as long as 260 ms and the device could not go off-channel without risking to miss the next DTIM beacon [interval ~307 ms].
