Reducing the retries of sending PS exit packets to the peer AP. That fix is to avoid sending unrealizable number of PS exit packets in case of ap lost. Signed-off-by:

Add support to FM WLAN coexistence (STA only). Some WiFi harmonics may interfere with FM operation, to avoid this problem special coexistence techniques are activated around some FM frequencies. Signed-off-by:

When working in ibss mode, we don't configure rate policy per station (as we use the same link for multiple stations), so currently the 1mb/s rate is being used. Instead, configure the firmware to use the whole 11b rates by default. Signed-off-by:

ieee80211_reconfig() sets most of the "changed" flags regardless of the actual change (e.g. BSS_CHANGED_ASSOC will be set even if the interface is still not associated). in this case the driver will issue some unneeded commands. Since the driver relies solely on the BSS_CHANGED_ASSOC flag, without checking if there was an actual change, it will end up issuing unjoin() and dummy_join() commands, although it was never associated and should just remain idle. Avoid it by checking the actual state change, in addition to the "changed" flag. (there seem to be more redundant configuration commands being issued, but they shouldn't harm) Signed-off-by:

When debugging, reduce the padding size from each rx packet, to get the actual packet size (so comparing it against a cap file will be easier) Signed-off-by:

Fix mismatch between the REF CLK and TCXO CLK information that is set in the platform data and the NVS, so we override what comes from the NVS and replace it with what comes from the platform data. [Small fix in a comment -- Luca] Signed-off-by:

The elp_work is being enqueued on wl1271_ps_elp_sleep, but doesn't get cancelled on wl1271_ps_elp_wakeup. This might cause immediate entrance to elp when the wl->mutex is being released, rather than using the delayed enqueueing optimization. Cancel elp_work on wakeup request, and add a new WL1271_FLAG_ELP_REQUESTED flag to further synchronize the elp actions. [Fixed a couple of typos in some comments -- Luca] Signed-off-by:

commit d05c806 ("wl12xx: rearrange some ELP wake_up/sleep calls") introduced a bug in which wl1271_ps_elp_wakeup() was called instead of wl1271_ps_elp_sleep() after completing the tx work. Reported-by:Arik Nemtsov <arik@wizery.com> Signed-off-by:

The tx_headroom required for mwl8k driver is 32 bytes and it can use the space for 802.11 header received from mac80211. mwl8k considers the smallest 802.11 frame (CTS2self of 10 bytes) that can be received from mac80211 to compute the extra_tx_headroom as 22 (32 - 10) bytes. When the wireless interface is part of bridge, this extra_tx_headroom requirement results in a memcpy in mac80211 (in function pskb_expand_head) for all the data frames needing L2 forwarding/bridging, when NET_SKB_PAD is defined as 32. This patch reduces the extra_tx_headroom by 8 bytes so that memcpy of data frames in mac80211 is avoided in this case. The resize will be required in driver for frames with 802.11 header size of less than 18 bytes. 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. Do not change callback, I did (and fixed) that mistake in iwlagn. Signed-off-by:

Since commit f844a709 Author: Stanislaw Gruszka <sgruszka@redhat.com> Date: Fri Jan 28 16:47:44 2011 +0100 iwlwifi: do not set tx power when channel is changing we set device tx power during initialization to priv->tx_power_next, which itself is initialized to minimum power. That changed default behaviour of driver. Previously we initialized device to transmit at maximum available power by default. Patch change again to previous behaviour and cleanup tx power initialization. Fortunately this is not critical fix, as mac80211 layer setup tx power lately to 14dB, hence device does not operate at minimal transmit power all the time. Signed-off-by:

Even for keys that shouldn't be stored some use cases require the knowledge of a new key having been created so that the conclusion of a successful pairing can be made. Therefore, always send the mgmt_new_key event but add a store_hint parameter to it to indicate to user space whether the key should be stored or not. Signed-off-by:

When accepting a pairing request which fulfills the SSP auto-accept criteria we need to push the request all the way to the user for confirmation. This patch adds a new hint to the user_confirm_request management event so user space can know when to show a numeric comparison dialog and when to show a simple yes/no confirmation dialog.

Some test systems require an arbitrary delay to the auto-accept test cases for Secure Simple Pairing in order for the tests to pass. Previously when this was handled in user space it was worked around by code modifications and recompilation, but now that it's on the kernel side it's more convenient if there's a debugfs interface for it.
