We know after loading the ucode whether it will support PAN or not, so we can also initialise the cmd_queue variable much earlier. Signed-off-by:

Devices newer than 4965 don't actually send two different versions of the ALIVE command, so we always had a bug here since before this patch we copy more data than we got. Remove the iwl_init_alive_resp struct and don't use it. Since we also really don't need to track all the data received in ALIVE as we only use the error and log event tables later, we can also save space by just keeping those and not more data around in memory.

My previous patch left a message talking about bootstrap, but that's clearly bogus. Signed-off-by:

Some new devices and microcode files will a greater variety of features, so the TLV-per-feature approach we took before will quickly make things harder to manage and increase the file size. Add a new TLV that has feature flags. Currently, it will contain: 1) a PAN feature flag, which moves from a separate TLV 2) a new BT stats bit that indicates whether the microcode image uses bluetooth statistics 3) a new MFP flag for management frame protection which can be enabled once the device/microcode supports it Signed-off-by: -

The ucode restart has to take into account a number of things, like clearing the HCMD_ACTIVE and other status bits, and waking up the wait_command_queue. Currently, however, there are a number of places that neither do that, nor actually set the FW error bit that leads to proper restart handling, which means that in those cases things will probably just hang completely. To clean this up, make all ucode restart go through a single function, except for the cases where it's called during firmware loading. Also fix a bug in wimax coexist restart avoidance, it needs to first clear the status bits (and it has to clear the HCMD_ACTIVE one as well) and then wake up anything waiting on wait_command_queue.

Only 4965 had a bootstrap microcode image, so the agn driver can completely ignore that and we can remove some code from it. Signed-off-by:

When we loaded a ucode, there's no point in checking any one that is present, we know which one is supposed to be present so also verify that it is exactly the right one. That also simplifies the code and makes it faster since it doesn't have to check all. Signed-off-by:

The code in iwlcore_verify_inst_sparse really doesn't need to keep track of the number of errors it encountered since a single one is fatal. Also, the code in iwl_verify_inst_full is just used to print out some things, so rename it to iwl_print_inst and don't give it a return code and just make it print out the values. Signed-off-by:

Current ath9k code does not handle beacon timers on opmode specific. One such example is that a STA beacon config overwrites already configured AP vif's beacon timers during scan. On multi station vif case, configure beacon timers beased on primary vif selected. This also helps while moving back to single STA vif from multi STA vifs, where the power save is enabled and hw has to be reconfigured with proper beacon and bssid/aid. Otherwise connection poll will be triggered so frequently due to beacon loss. Signed-off-by:

As of now bssid/aid is overridden with recently changed vif's bss config. This may cause improper beacon updation due to bssid/aid mismatch. On station mode, select an associated sta vif as primary vif and configure that vif's bss into hw. Update the primary vif on interface change and bss info change. Signed-off-by:

On Nokia N900 the wl1251 consumes the most power when the interface is up but not associated to access point (that supports PSM). In terms of battery current consumption, the consumption is ~180 mA higher when the interface is up but not associated and only ~5 mA higher when associated compared to interface down and driver not loaded cases. This patch adds support for the mac80211 idle notifications. Chip is put into idle very much the same way when entering into PSM by utilizing the Extreme Low Power (ELP) mode. I.e. idle is entered by setting necessary conditions in wl1251_ps_set_mode followed by a call to wl1251_ps_elp_sleep. It seems it is just enough the authorize ELP mode followed by CMD_DISCONNECT (thanks to Kalle Valo about the idea to use it). Without disconnect command the chip remains somewhat active and stays consuming ~20 mA. Idle mode is left by same way than PSM. The wl1251_join call is used to revert the CMD_DISCONNECT. Without it association to AP doesn't work when trying second time. With this patch the interface up but not associated case the battery current consumption is less than 1 mA higher compared to interface down case. Signed-off-by:

RFC for WL1251 idle mode support brought a few issues that are worth to update before adding the idle mode support. Since the idle mode can reuse the code that is now used in Power Save Mode (PSM), the flag psm in struct wl1251 is changed to variable station_mode to be able to distinguish between PSM and idle modes. As the station mode is different than the power power save mode command that is sent to chip, the enum wl1251_cmd_ps_mod values are used only when communicating with the chip and new enum wl1251_station_mode values are used inside the driver. Confusing comment about psm and elp relation is removed since the PSM is actually activated by putting the chip into Entreme Low Power (ELP) mode. Signed-off-by:

With compat-wireless CR* macros in zd_usb.h conflict with CR macros in include/asm-generic/termbits.h. So rename CR* macros to ZD_CR*. Conversion was done with using sed and then 'over 80 character line' checkpatch.pl warnings and comment indents were fixed. Reported-by:

The recent cleanups in the beacon code fixed SWBA backoff calculation, however it did not remove a line of code that worked around the issues from the earlier version of the code. After the cleanup, the initial TSF based slot calculation now always returns 0 instead of ATH_BCBUF-1, so the previous hack that reversed the slot order needs to be removed, as ad-hoc mode does not use staggered beacons.

When testing wpa_supplicant with 'nl80211' driver to connect to an AP with WPA/WPA2 security, we notice the followings: 1) add_key is called firstly with the key from cfg80211 2) set_defaut_key is called next set_default_key() is specific to WEP keys and should not be called in case of WPA/WPA2 security. The set_default_key() won't be called if wpa_supplicant uses "-Dwext" option, but it's been called if "-Dnl80211" option is specified. We can fix this issue by adding a check to return from set_default_key() if WEP key is not configured. Signed-off-by:

Check status bits with mutex taken, because when we wait for mutex unlock, status can change. Patch should also make remaining sync commands be send with priv->mutex taken. That will prevent execute these commands when we are currently reset firmware, what could possibly cause troubles. Signed-off-by:

We mark command as huge by using meta->flags from other (non huge) command, but flags can be possibly overridden, when non huge command is enqueued, what can lead to: WARNING: at lib/dma-debug.c:696 dma_debug_device_change+0x1a3/0x1f0() DMA-API: device driver has pending DMA allocations while released from device [count=1] To fix introduce additional CMD_MAPPED to mark command as mapped and serialize iwl_enqueue_hcmd() with iwl_tx_cmd_complete() using hcmd_lock. Serialization will also fix possible race conditions, because q->read_ptr, q->write_ptr are modified/used in parallel. On the way fix whitespace. Signed-off-by:
