In AP mode, configure the fw to pass beacons from foreign APs, in order to be able to set the ht protection IE properly.

Firmware folks seem say that this flag can make trouble. Drop it. The advantage of CTS to self is that it slightly reduces the cost of the protection, but make the protection less reliable. Cc: <stable@vger.kernel.org> [3.13+] Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2014-06-24iwlwifi: mvm: Fix broadcast filteringIlan Peer
Current code did not allow sending the broadcast filtering command for P2P Client interfaces. However, this was not enough, since once broadcast filtering command was issued over the station interface after the P2P Client connected, the command also attached the filters to the P2P Client MAC which is not allowed (FW ASSERT 1063).

2014-06-24iwlwifi: mvm: rework sched scan channel configurationEliad Peller
The current sched scan channel configuration code configures all the supported channels for scanning. However, this can result in SYSASSERT in some cases, when the configured channel is disabled. Instead, configure only the channels given in the req struct, and set the channel_count field appropriately. While on it, change the code to use channel->hw_value instead of recalculating the channel number.

2014-05-21iwlwifi: mvm: pass force_assoc_off all the way down to avoid hacksLuciano Coelho
In some cases, we need to force the association to be off in the MAC_CONTEXT_CMD command we send to the firmware. Instead of having to hack the vif->bss_conf.assoc value, pass it all the way down the call chain. Additionally, for the iwl_mvm_mac_ctxt_add() case, we *always* set forced_assoc_off to true, so we can remove the hack in the d3 code that was forcing it to off by hacking the bss_conf.assoc value.

2014-05-11iwlwifi: mvm: Disable uAPSD for a DCM clientAvri Altman
A binding object associates virtual MACs to a Phy. Binding object can ask (and get) air time, thus allowing several MACs to share the medium. A binding object can be in either one of 3 states: 1) standalone - A single active MAC 2) Different Channel Mode (DCM) - There are 2 active MACs or more (not necessarily just clients), but each has its own channel. 3) Same Channel Mode (SCM) - There are 2 active MACs or more (not necessarily just clients), that share the same channel. This patch introduces an additional condition for enabling uAPSD: uAPSD should be disabled for a client in DCM. The reason for that is a low latency issue in Miracast.
