2014-03-17brcmfmac: assure active clock request upon entering SLEEP stateArend van Spriel
When the SDIO driver goes in low power state it must assure that a clock request in ChipCLKCSR is set. Otherwise waking up the device can fail. The register is read and if necessary the ALP clock will be requested.

2014-03-17brcmfmac: Improve scanning settings for connect.Hante Meuleman
When connecting without specifying the channel it can take quite some time to connect. This is because not all parameters for the scan operation are set to optimized values. This patch changes these parameters resulting in a much faster connect in certain situations.

2014-03-17brcmfmac: Protect tx seq number for data and controlHante Meuleman
SDIO tx uses a sequence number which is common for data and control. This requires that access to this sequence number is protected. A mutex was used to achieve this, but it also required the reordering of code for tx control.

2014-03-17can: populate netdev::dev_id for udev discriminationChristopher R. Baker
My objective is to be able to totally discriminate CAN ports on multi-port cards via udev so as to rename them to semantically interesting/unique names for my system (e.g., "ecuCAN" and "auxCAN" instead of "can0" and "can1"). The following patch assigns the dev_id field to match the channel number on all multi-channel devices. I can only test my two-port Peak PCI card, but it works as expected: ATTRS{dev_id} now expresses the port number and my udev rules now unambiguously pick out and rename my individual CAN ports.

2014-03-17can: Unify MTU settings for CAN interfacesOliver Hartkopp
CAN interfaces only support MTU values of 16 (CAN 2.0) and 72 (CAN FD). Setting the MTU to other values is pointless but it does not really hurt. With the introduction of the CAN FD support in drivers/net/can a new function to switch the MTU for CAN FD has been introduced. This patch makes use of this can_change_mtu() function to check for correct MTU settings also in legacy CAN (2.0) devices.

Enable protocol offloading (arp and NS) on D0i3. The offloading allows the fw answer NS and arp requests without waking up the host. Since protocol offloading is saved between D0i3 entries, we have to explicitly disable it in case we don't want it.

2014-03-16iwlwifi: mvm: reconfigure qos seq on D0i3 exitArik Nemtsov
In order to restore the qos seq number on d0i3 exit, we need to read it from the wowlan status. However, in order to make sure we use correct seq num for tx frames, we need to defer any outgoing frames, and re-enqueue them only after the seq num is configured correctly. Sync new Tx aggregations with D0i3 so that the correct seq num is used for them. Wait synchronously for D0i3 exit before starting a new Tx agg.

Enable beacon filter only if at least one beacon from candidate AP is received before or after association. Check this condition before enabling BF upon secured association completion. Add BF enablement to mac80211 event that indicates beacon is received after association. Too early beacon filtering enablement can lead to disconnection due to missing AP's beacon after association.

Instead of failing without any notice to the user, fallback to the default mode (RF mode) if the blink mode is selected and print an error to inform the user.
