iwl4965: reset firmware after rfkill off

2013-08-20T15:43:03+00:00

commit 788f7a56fce1bcb2067b62b851a086fca48a0056 upstream.

Using rfkill switch can make firmware unstable, what cause various
Microcode errors and kernel warnings. Reseting firmware just after
rfkill off (radio on) helped with that.

iwl4965: set power mode early

2013-08-20T15:43:03+00:00

commit eca396d7a5bdcc1fd67b1b12f737c213ac78a6f4 upstream.

If device was put into a sleep and system was restarted or module
reloaded, we have to wake device up before sending other commands.
Otherwise it will fail to start with Microcode error.

iwlwifi: dvm: don't send BT_CONFIG on devices w/o Bluetooth

2013-08-12T01:35:26+00:00

commit 707aee401d2467baa785a697f40a6e2d9ee79ad5 upstream.

The BT_CONFIG command that is sent to the device during
startup will enable BT coex unless the module parameter
turns it off, but on devices without Bluetooth this may
cause problems, as reported in Redhat BZ 885407.

Fix this by sending the BT_CONFIG command only when the
device has Bluetooth.

iwlwifi: mvm: set SSID bits for passive channels

2013-08-12T01:35:26+00:00

commit bb963c4a43eb5127eb0bbfa16c7a6a209b0af5db upstream.

Set SSID bitmap for direct scan even on passive channels,
for the passive-to-active feature. Without this patch only
the SSID from probe request template is sent on passive
channels, after passive-to-active switching, causing us to
not find all desired networks.

Remove the unused passive scan mask constant.

mwifiex: check for bss_role instead of bss_mode for STA operations

2013-08-12T01:35:23+00:00

commit 953b3539ef9301b8ef73f4b6e2fd824b86aae65a upstream.

This patch fixes an issue wherein association would fail on P2P
interfaces. This happened because we are checking priv->mode
against NL80211_IFTYPE_STATION. While this check is correct for
infrastructure stations, it would fail P2P clients for which mode
is NL80211_IFTYPE_P2P_CLIENT.

Better check would be bss_role which has only 2 values: STA/AP.

rt2x00: fix stop queue

2013-08-12T01:35:23+00:00

commit e2288b66fe7ff0288382b2af671b4da558b44472 upstream.

Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following
call to rt2x00queue_pause_queue() reduce to noop, i.e we do not
stop queue in mac80211.

To fix that introduce rt2x00queue_pause_queue_nocheck() function,
which will stop queue in mac80211 directly.

Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit.

Note also that reordering operations i.e. first call to
rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race
with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue()
directly is the only available solution to fix the problem without
major rework.

ath: wil6210: Fix build error

ath9k_htc: reboot firmware if it was loaded

2013-08-12T01:35:22+00:00

commit 4928bd2ef8ece262f4f314630219999a91eaa440 upstream.

Currently ath9k_htc will reboot firmware only if interface was
ever started. Which lead to the problem in case where interface
was never started but module need to be reloaded.

This patch will partially fix bug "ath9k_htc: Target is unresponsive"
https://github.com/qca/open-ath9k-htc-firmware/issues/1

Reproduction case:
- plug adapter
- make sure nothing will touch it. Stop Networkmanager or blacklist mac address of this adapter.
- rmmod ath9k_htc; sleep 1; modprobe ath9k_htc
