2010-11-11vxge: correct multi-function detectionJon Mason
The values used to determined if the adapter is running in single or multi-function mode were previously modified to the values necessary when making the VXGE_HW_FW_API_GET_FUNC_MODE firmware call. However, the firmware call was not modified. This had the driver printing out on probe that the adapter was in multi-function mode when in single function mode and vice versa.

2010-11-11vxge: Wait for Rx to become idle before reseting or closingJon Mason
Wait for the receive traffic to become idle before attempting to close or reset the adapter. To enable the processing of packets while Receive Idle, move the clearing of __VXGE_STATE_CARD_UP bit in vxge_close to after it. Also, modify the return value of the ISR when the adapter is down to IRQ_HANDLED. Otherwise there are unhandled interrupts for the device.

2010-11-09ath9k_hw: optimize all descriptor access functionsFelix Fietkau
Because all of the descriptor data structures are marked as __packed, GCC assumes the worst case wrt. alignment and generates unaligned load/store instructions on MIPS for access to all fields. Since descriptors always have to be 4-byte-aligned, we can just mark the data structures with __aligned(4), which allows GCC to generate much more efficient code. Verified through disassembly and OProfile comparisons. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-09ath9k: Convert to new PCI PM frameworkRafael J. Wysocki

2010-11-09ath9k: optimize/fix ANI RSSI processingFelix Fietkau
ANI needs the RSSI average only in station mode, and only for tracking the signal strength of beacons of the AP that it is connected to. Adjust the code to track on the beacon RSSI, and store the average of that in the ath_wiphy struct. With these changes, we can get rid of this extra station lookup in the rx path, which saves precious CPU cycles. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2010-11-09ath9k_hw: optimize tx status descriptor processingFelix Fietkau
Disassembly shows, that at least on MIPS, the compiler generates a lot of memory accesses to the same location in the descriptor field parsing. Since it is operating on uncached memory, this can be quite expensive in this hot path.

2010-11-09ath9k_hw: small optimization in ar9002_hw_get_isrFelix Fietkau
ah->config.rx_intr_mitigation does not need to be checked before checking the rx interrupt mask for AR_ISR_RXMINTR or AR_ISR_RXINTM, as those interrupts will be masked out if rx interrupt mitigation is disabled.

2010-11-09ath9k_hw: optimize interrupt mask changesFelix Fietkau
OProfile showed that ath9k was spending way too much time in ath9k_hw_set_interrupts. Since most of the interrupt mask changes only need to globally enable/disable interrupts, it makes sense to split this part into separate functions, replacing all calls to ath9k_hw_set_interrupts(ah, 0) with ath9k_hw_disable_interrupts(ah). ath9k_hw_set_interrupts(ah, ah->imask) only gets changed to ath9k_hw_enable_interrupts(ah), whenever ah->imask was not changed since the point where interrupts were disabled.

2010-11-08ath9k_htc: Fix probe failure if CONFIG_USB_DEBUG enabledRajkumar Manoharan
Since the endpoint descriptors (EP3 & EP4) were changed from Interrupt to Bulk type by firmware, the urb submission done on Bulk pipes. And the recent commit "check the endpoint type against the pipe type" added aditional error checking against pipe types under CONFIG_USB_DEBUG.

2010-11-08ath9k_hw: Fix AR9280 surprise removal during frequent idle on/offVasanthakumar Thiagarajan
Bit 22 of AR_WA should be set to fix the situation where chip reset is asynchronous to clock of analog shift registers, such that when reset is released, it could mess up the values of analog shift registers and cause some hw issue on AR9280. This bit is write only, but the driver does a read-modify-write on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave() during radio disable. This causes surprise removal of hw. It can never recover from this state and the hw will become usable only after a power on/off cycle, and sometimes only during a cold reboot. This issue can be triggered by doing frequent roaming with the simple/test-roam script available from the wifi-test project [1] when roaming between APs quickly. When roaming there is a is a high possibility that the device being put into idle (radio disable) state by mac80211 during AUTH->ASSOC. A device hardware reset would fail and the kernel would output: [40251.363799] ath: AWAKE -> FULL-SLEEP [40251.363815] ieee80211 phy17: device no longer idle - working [40251.363817] ath: Marking phy17 as not-idle [40251.363819] ath: FULL-SLEEP -> AWAKE [40251.415978] pciehp 0000:00:1c.3:pcie04: Card not present on Slot(3) [40251.419896] ath: ah->misc_mode 0x4 [40251.428138] pciehp 0000:00:1c.3:pcie04: Card present on Slot(3) [40251.532247] ath: timeout (100000 us) on reg 0x9860: 0xffffffff & 0x00000001 != 0x00000000 [40251.532250] ath: Unable to reset channel (2462 MHz), reset status -5 [40251.532422] ath: Set channel: 5745 MHz [40251.540639] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.548826] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.557023] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.565211] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.573415] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.581603] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.581606] ath: Failed to stop TX DMA.

2010-11-08libipw: fix proc entry removalLinus Torvalds
This bug seems to be due to commit 27ae60f8f7aac ("ipw2x00: replace "ieee80211" with "libipw" where appropriate"), where Pavel did this: - libipw_proc = proc_mkdir(DRV_NAME, init_net.proc_net); + libipw_proc = proc_mkdir("ieee80211", init_net.proc_net); but then the cleanup was kept as remove_proc_entry(DRV_NAME, init_net.proc_net); in both places (both in the failure case and in the unload case). The error string is also total crap, and says "Unable to create " DRV_NAME " proc directory\n"); Even though it doesn't actually create a proc directory named DRV_NAME at all. So that patch looks like total and utter crap to me. The commit message says "Keep /proc/net/ieee80211 under the original name to avoid breaking user interface." but the thing is, it really didn't fix anything but that one create thing.
