Setting up the CAB queue requires only the beacon interval, remove the function ath_get_beaconconfig() which is redundant. Signed-off-by:

This extends the NL80211_CMD_TRIGGER_SCAN command to allow applications to specify a set of information element(s) to be added into Probe Request frames with NL80211_ATTR_IE. This provides support for the MLME-SCAN.request primitive parameter VendorSpecificInfo and can be used, e.g., to implement WPS scanning. Signed-off-by:

We currently send beacons directly from the interrupt routine. This can hold up interrupt processing in beaconing modes and makes the ISR somewhat more complex. Move it to a tasklet like rx and tx. Changes-licensed-under: 3-Clause-BSD Signed-off-by:

ath5k_reset can be called from process context, which in turn can call ath5k_beacon_config which takes the sc->block spinlock. Since it can also be taken in hard irq context, use spin_lock_irqsave everywhere. This fixes a potential deadlock in adhoc mode.

Since interrupts are already masked by the hardware, there's no need to discard interrupt bits in the ISR itself. Also, in ath5k_beacon_config we mask off a couple of bits without locking, so doing this mask in software can lead to unhandled beacon timer and beacon miss interrupts.

The only way rf_write() can be called with word 0 is when the user sends the wrong word index through debugfs. However the values which are send through debugfs are validated using the RF_BASE and RF_SIZE macro values, the most logical solution is to increase RF_BASE with 4 and decrease RF_SIZE with 4 (RF_SIZE has always been 1 word too big) Signed-off-by:

Fixes: - iwlwifi is an optional driver and should thus not default to 'y'. - 3945 now depends on IWLCORE. Rework: - There is not a case when IWLCORE should not be selected. At the same time the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of these two. With IWLWIFI being the driver name we proceed to use just it and replace instances of IWLCORE with it. The module name does not change and is still iwlcore. - Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move this up to one select when IWLWIFI is selected. - IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series. - Now that 3945 depends on IWLWIFI we can also indicate its dependency on MAC80211_LEDS and LEDS_CLASS at this level. - IWLAGN_LEDS is not used by driver - remove it. - IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part of iwlcore module. Move this config up in Kconfig to reflect that and also change name to IWLWIFI_SPECTRUM_MEASUREMENT. - CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to description that indicates this. - CONFIG_IWL3945_RFKILL does not exist - remove usage from driver. - Add "iwlagn" to end of description of IWLAGN to help people understand what iwlagn means in rest of Kconfig text. - Add "iwl3945" to end of description of IWL3945 to help people understand what iwlagn means in rest of Kconfig text. - Change IWLWIFI_DEBUGFS description to indicate that only iwlagn supports it (for now).

- some of them are defined as follows: #define ipw_write32 expr1; expr2 and are called from loops or ifs without a compound statement, so they are broken. Fix it by putting them into do {} while (0) for writes and ({ }) for reads. - also unify and cleanup them while at it -- convert them from macros to inline functions, so that we get some basic typechecking Signed-off-by:Jiri Slaby <jirislaby@gmail.com> Acked-by:

Both branches of the regulatory check in ath_attach() set up a custom regulatory domain and apply radar and world flags, so extract those into a single path. While at it, fix a couple of spelling errors and an unnecessary extra pointer traversal. Signed-off-by:

This avoids triggering a BUG_ON in pci_disable_msi in the error path. Furthermore remove the first call to pci_disable_device as it is already called at out_pci_disable_device. Both issues were introduced in the patch "iwlagn: fix hw-rfkill while the interface is down". Signed-off-by:

The AP can switch dynamically between 20/40 Mhz channel width, in which case we switch the local operating channel, but the rate control algorithm is not notified. This patch adds a new callback to indicate such changes to the RC algorithm. Currently, HT channel width change is notified, but this callback can be used to indicate any new requirements that might come up later on. Signed-off-by:

This patch splits out the ibss code and data from managed (station) mode. The reason to do this is to better separate the state machines, and have the code be contained better so it gets easier to determine what exactly a given change will affect, that in turn makes it easier to understand. This is quite some churn, especially because I split sdata->u.sta into sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that way. I've also shuffled around some code -- null function sending is only applicable to managed interfaces so put that into that file, some other functions are needed from various places so put them into util, and also rearranged the prototypes in ieee80211_i.h accordingly.

Hardware with AMPDU queues currently has broken aggregation. This patch fixes it by making all A-MPDUs go over the regular AC queues, but keeping track of the hardware queues in mac80211. As a first rough version, it actually stops the AC queue for extended periods of time, which can be removed by adding buffering internal to mac80211, but is currently not a huge problem because people rarely use multiple TIDs that are in the same AC (and iwlwifi currently doesn't operate as AP). This is a short-term fix, my current medium-term plan, which I hope to execute soon as well, but am not sure can finish before .30, looks like this: 1) rework the internal queuing layer in mac80211 that we use for fragments if the driver stopped queue in the middle of a fragmented frame to be able to queue more frames at once (rather than just a single frame with its fragments) 2) instead of stopping the entire AC queue, queue up the frames in a per-station/per-TID queue during aggregation session initiation, when the session has come up take all those frames and put them onto the queue from 1) 3) push the ampdu queue layer abstraction this patch introduces in mac80211 into the driver, and remove the virtual queue stuff from mac80211 again This plan will probably also affect ath9k in that mac80211 queues the frames instead of passing them down, even when there are no ampdu queues.
