2013-06-25iwlwifi: mvm: Change the settings of AP beacon timeIlan Peer1-5/+51
In case that an AP/GO interface is started while there is a station/P2P client associated, need to make sure that the AP/GO beacon time is far enough from the station's one in oder to allow the station to receive the DTIM beacons and the following traffic etc. To resolve this, when the AP is started, check if there is an active station interface, and guarantee that the AP/GO TBTT is far enough from the station one.

Unfortunately this means that the driver in 3.9 and 3.10 can't work, but that's still better than crashing the device/driver there. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-06-13iwlwifi: pcie: wake the queue if stopped when being unmappedEmmanuel Grumbach1-0/+3
When the queue is unmapped while it was so loaded that mac80211's was stopped, we need to wake the queue after having freed all the packets in the queue. Not doing so can result in weird stuff like: * run lots of traffic (mac80211's queue gets stopped) * RFKILL * de-assert RFKILL * no traffic Cc: stable@vger.kernel.org Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-06-13iwlwifi: pcie: fix race in queue unmappingEmmanuel Grumbach1-0/+10
When a queue is disabled, it frees all its entries. Later, the op_mode might still get notifications from the firmware that triggers to free entries in the tx queue. The transport should be prepared for these races and know to ignore reclaim calls on queues that have been disabled and whose entries have been freed.

The older devices (pre-7000/3000 series) all only work with the DVM opmode due to firmware availability, while newer ones will only work with the MVM opmode for the same reason. When building a driver that only has one of MVM or DVM, there's no reason to build the device support and have the PCIe IDs for all devices since they can't be used anyway, so avoid that.

According to the FW implementation, the quota command should have a valid entry for each active binding (where 'active' in this context means that the binding is known to the FW). In case the binding should not get any quota, the 'quota' should be set to zero. Not setting an 0 quota for an active binding when all the MACs in the binding are idle, i.e., not associated in case of managed interface, will result in preventing the FW scheduler from entering IDLE state and the FW from transitioning to low PS.
