2014-02-06ath9k: Disable cross-band FCCSujith Manoharan
commit 1e2f9295f4c657500111514f92a3d3894d0e05b4 upstream. Fast Channel Change across bands was enabled for AR9462 recently, but this is causing baseband issues. Disable it until this feature is tested well. Also, remove the feature bit for AR9565 since it is a single-band card and doesn't support this feature.

2014-02-06ath9k: Use correct channel for RX packetsSujith Manoharan
commit ff9a93f2ebb88ac7aab9568de80b64b92078e96d upstream. Accessing the current channel definition in mac80211 when processing RX packets is problematic because it could have been updated when a scan is issued. Since a channel change involves flushing the existing packets in the RX queue before a chip-reset is done, they would be processed using the wrong band/channel information. To avoid this, use the current channel information maintained in the driver.

2014-02-06iwlwifi: pcie: enable oscillator for L1 exitEmmanuel Grumbach
commit 2d93aee152b1758a94a18fe15d72153ba73b5679 upstream. Enabling the oscillator consumes slightly more power (100uA) but allows to make sure that we exit from L1 on time. Not doing so might lead to a PCIe specification violation since we might wake up from L1 at the wrong time. This issue has been identified on 3160 and 7260 only. On older NICs L1 off is not enabled, on newer NICs (7265), the issue is fixed. When the bug occurs the user sees that the NIC has disappeared from the PCI bridge, any access to the device returns 0xff. This fixes: https://bugzilla.kernel.org/show_bug.cgi?id=64541 and has been extensively discussed here: http://markmail.org/thread/mfmpzqt3r333n4bo Fixes: 99cd47142399 ("iwlwifi: add 7000 series device configuration") Reported-and-tested-by: wzyboy <wzyboy@wzyboy.org> Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-01-10net: core: explicitly select a txq before doing l2 forwardingJason Wang
Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

2013-11-25iwlwifi: mvm: BT Coex - don't enable MULTI_PRIO_LUTEmmanuel Grumbach
This feature isn't supported by the firmware (yet). Note that settingt he values to BT_CFG_CMD is harmless if the validity bit is clear - so keep the configuration values in BT_CFG_CMD, but clear the validity bit until thes feature is enabled in the firmware.

2013-11-25iwlwifi: pcie: fix interrupt coalescing for 7260 / 3160Emmanuel Grumbach
We changed the timeout for the interrupt coealescing for calibration, but that wasn't effective since we changed that value back before loading the firmware. Since calibrations are notification from firmware and not Rx packets, this doesn't change anyway - the firmware will fire an interrupt straight away regardless of the interrupt coalescing value. Also, a HW issue has been discovered in 7000 devices series. The work around is to disable the new interrupt coalescing timeout feature - do this by setting bit 31 in CSR_INT_COALESCING. This has been fixed in 7265 which means that we can't rely on the device family and must have a hint in the iwl_cfg structure.

2013-11-25iwlwifi: mvm: check sta_id/drain values in debugfsJohannes Berg
The station ID must be valid, if it's out of range then the array access may crash. Validate the station ID to the array length, and also validate the drain value even if that doesn't matter all that much.
