rt2800: fix RT5390 & RT3290 TX power settings regression

2013-07-03T17:55:22+00:00

commit 8c8d2017ba25c510ddf093419048460db1109bc4 upstream.

    rt2800: use BBP_R1 for setting tx power

unfortunately does not work well with RT5390 and RT3290 chips as they
require different temperature compensation TX power settings (TSSI
tuning). Since that commit make wireless connection very unstable on
those chips, restore previous behavior to fix regression. Once we
implement proper TSSI tuning on 5390/3290 we can restore back setting
TX power by BBP_R1 register for those chips.

iwlwifi: dvm: fix chain noise calibration

2013-07-03T17:55:21+00:00

commit b28b6dfe580ab1ab8bf08b908fd69e299b877103 upstream.

First step of chain noise calibration process had disable flag
check inverted. Chain noise calibration never started because
of this.

Tested on intel 5300 with two antennas attached. The driver
correctly disabled one chain.

ath9k_htc: Handle IDLE state transition properly

2013-07-03T17:55:21+00:00

commit 075163bbb0f51174359947e1bce84f5edb23f21e upstream.

Make sure that a chip reset is done when IDLE is turned
off - this fixes authentication timeouts.

carl9170: fix frame drop and WARN due to minstrel_ht change

2013-06-27T17:38:44+00:00

commit 5f34608fa2acbfef5a06d0072a978c9943c28a2d upstream.

With "mac80211/minstrel_ht: add support for using CCK rates"
minstrel_ht selects legacy CCK rates as viable rates for
outgoing frames which might be sent as part of an A-MPDU
[IEEE80211_TX_CTL_AMPDU is set].

This behavior triggered the following WARN_ON in the driver:
> WARNING: at carl9170/tx.c:995 carl9170_op_tx+0x1dd/0x6fd
The driver assumed that the rate control algorithm made a
mistake and dropped the frame.

This patch removes the noisy warning altogether and allows
said A-MPDU frames with CCK sample and/or fallback rates to
be transmitted seamlessly.

brcmfmac: Turn off ARP offloading when configured for AP.

2013-06-27T17:38:25+00:00

commit b3657453f16a7b84eab9b93bb9a9a2901ffc70af upstream.

ARP offloading should only be used in STA or P2P client mode. It
is currently configured once at init. When being configured for AP
ARP offloading should be turned off and when AP mode is left it can
be turned back on.

rtlwifi: rtl8192cu: Fix problem in connecting to WEP or WPA(1) networks

commit 5b8df24e22e0b00b599cb9ae63dbb96e1959be30 upstream.

Driver rtl8192cu can connect to WPA2 networks, but fails for any other
encryption method. The cause is a failure to set the rate control data
blocks. These changes fix https://bugzilla.redhat.com/show_bug.cgi?id=952793
and https://bugzilla.redhat.com/show_bug.cgi?id=761525.

wl12xx: fix minimum required firmware version for wl127x multirole

2013-06-20T19:01:30+00:00

commit 60c28cf18f970e1c1bd40d615596eeab6efbd9d7 upstream.

There was a typo in commit 8675f9 (wlcore/wl12xx/wl18xx: verify
multi-role and single-role fw versions), which was causing the
multirole firmware for wl127x (WiLink6) to be rejected.  The actual
minimum version needed for wl127x multirole is 6.5.7.0.42.

ath9k: Use minstrel rate control by default

2013-06-20T19:01:29+00:00

commit 5efac94999ff218e0101f67a059e44abb4b0b523 upstream.

The ath9k rate control algorithm has various architectural
issues that make it a poor fit in scenarios like congested
environments etc.

An example: https://bugzilla.redhat.com/show_bug.cgi?id=927191

Change the default to minstrel which is more robust in such cases.
The ath9k RC code is left in the driver for now, maybe it can
be removed altogether later on.

commit 96005931785238e1a24febf65ffb5016273e8225 upstream.

This reverts commit 68d9e1fa24d9c7c2e527f49df8d18fb8cf0ec943

This change reduces rx sensitivity with no apparent extra benefit.
It looks like it was meant for testing in a specific scenario,
but it was never properly validated.

ath9k: Disable PowerSave by default

2013-06-20T19:01:28+00:00

commit 531671cb17af07281e6f28c1425f754346e65c41 upstream.

Almost all the DMA issues which have plagued ath9k (in station mode)
for years are related to PS. Disabling PS usually "fixes" the user's
connection stablility. Reports of DMA problems are still trickling in
and are sitting in the kernel bugzilla. Until the PS code in ath9k is
given a thorough review, disbale it by default. The slight increase
in chip power consumption is a small price to pay for improved link
stability.
