When an application asks for a latency lower than the beacon interval there's nothing we can do -- we need to stay awake and not have the AP buffer frames for us. Add code to automatically calculate this constraint in mac80211 so drivers need not concern themselves with it. Signed-off-by:

When you have multiple virtual interfaces the current implementation requires setting them up properly from userspace, which is undesirable when we want to default to power save mode. Keep track of powersave requested from userspace per managed mode interface, and only enable powersave globally when exactly one managed mode interface is active and has powersave turned on. Second, only start the dynPS timer when PS is turned on, and properly turn it off when PS is turned off. Third, fix the scan_sdata abuse in the dynps code. Finally, also reorder the code and refactor the code that enables PS or the dynps timer instead of having it copied in two places. Signed-off-by:

This patch deactivates powersave in station mode. It does not work correctly yet, so the code does more harm than good. (I split the original patch and sent part of it for 2.6.30, which didn't have the IEEE80211_HW_BEACON_FILTER flag. -- JWL) Reported-by:

When the EEPROM is not in good condition we cannot continue so we currently bail out but only ath5k is bailing out properly. Both ath9k and ar9170 were proceeding and if a user were to run into this they'd see an obscure panic. Lets propagate the error as intended and make sure we inform the user by lifting the error message from debug to a kernel error.

Grabbing an ath5k_buf then dropping the lock is racy because the referenced descriptor can be obtained in another thread and released before the buffer is handed to the hardware. Likewise, manipulating sc->rxlink without the lock can lead to having multiple self-linked hardware descriptors. Changes-licensed-under: 3-Clause-BSD Signed-off-by:

This patch simplifies the code used to detect when the self-linked DMA buffer is still in use by hardware, by checking the hardware's rxdp register instead of looking at the software buffer list. Signed-off-by:

Some hardware defects may require the hardware to be re-initialised completely from scratch. Drivers would need much information (for instance the current MAC address, crypto keys, beaconing information, etc.) stored duplicated from mac80211 to be able to do this, so let mac80211 help them. The new ieee80211_restart_hw() function requires the same code as resuming, so move that code into a new ieee80211_reconfig() function in util.c and leave only the suspend code in pm.c.

This message appears to be nothing more than a leftover of the experimental-8187B era. Also, we print the HW type in the hwaddr line, making this message reduntant. And it's definitely not important enough to be a KERN_WARNING. Signed-off-by:

ath9k_hw_getisr() doesn't appear to set anything in the status mask for PCI FATAL or PERR interrupts (AR_INTR_SYNC_HOST1_FATAL/PERR), which the open-source HAL seems to do. This means that the card isn't reset after these interrupts. This patch seems to fix a problem where the wireless drops out with an "ath9k: received PCI FATAL interrupt" in dmesg after some time; the hardware is an AR5416 in an ASUS WL-500W running 2.6.28.7 (OpenWRT) and compat-wireless 2009-03-31.

This patch fixes a bug introduced by commit "iwlwifi: adding MIMO3 support in rate scaling". We should not set the dual_stream_ant_msk (for 2x2 MIMO) when using a 3x3 rate, this will cause a SYSASSERT in uCode. Note: there is no triple_stream_ant_msk, because all three antennas are used.
