John W. Linville says: ==================== pull request: wireless-next 2014-07-03 Please pull this first batch of wireless updates intended for the 3.17 stream... For the mac80211 bits, Johannes says: "The biggest thing here is probably Arik's TDLS rework, beyond that we have smaller improvements and features like David's scanning IE thing, Luca's queue work, some CSA work, etc. Also your PID rate control removal, of course." For the iwlwifi bits, Emmanuel says: "I have here a whole bunch of various things. Andy contributes better debug prints for dvm specific flows and a module parameter to completely disable power save for dvm. Andrei is sharing the premises of his work on CSA - more to come. Eran and Liad keep on working on the new devices. I have the regular amount of BT Coex stuff and I continue to work on the firmware error report system adding more debug capabilities. More to come on that subject too." On top of that, there are some cleanups to the new rsi driver, some continuing improvements to the rtl818x drivers, and the usual bundles of updates to ath9k, b43, mwifiex, wil6210, and a few other bits here and there. ==================== Signed-off-by: David S.

2014-07-07iwlwifi: mvm: Use CS tx block bit for AP/GOAndrei Otcheretianski7-3/+136
An AP/GO may perform the channel switch slightly before its stations. This scenario may result in packet loss, since the transmission may start before the client is actually on a new channel. In order to prevent potential packet loss disable tx to all the stations when the channel switch flow starts. Clear the disable_tx bit when a station is seen on a target channel, or after IWL_MVM_CS_UNBLOCK_TX_TIMEOUT beacons on a new channel. In addition call ieee80211_sta_block_awake in order to inform mac80211 that the frames for this station should be buffered.

2014-07-07iwlwifi: mvm: Reflect GO channel switch in NoAAndrei Otcheretianski6-10/+153
According to the spec, GO/AP should perform the channel switch just before "beacon 0". However, since the exact timing isn't defined, it may result in a sudden GO disappearance from the channel. Prevent potential packet loss when performing the CS by scheduling NoA time event and executing the channel switch flow when a notification from fw is received.

Implement the switch_vif_chanctx operation with support for a single-vif and SWAP mode. The REASSIGN mode and multi-vifs are not supported yet. This operation needs to implement 4 steps, namely unassign, remove, add and assign the chanctx. In order to do this, split out these operations into locked and non-locked parts, thus allowing us to call them while locked. Additionally, in order to allow us to restart the hardware when something fails, add a boolean to the iwl_mvm_nic_restart() function that tells whether the restart was triggered by a FW error or something else.

2014-07-07iwlwifi: mvm: remove update type argument from quota updateJohannes Berg4-62/+19
It turns out that adding the update type argument was pointless as quota update is never called from the add_interface() callback. Therefore, IWL_MVM_QUOTA_UPDATE_TYPE_NEW isn't actually needed and then only a "disabled_vif" argument is needed for the upcoming CSA work. Remove the whole enum iwl_mvm_quota_update_type and pass the right arguments (always NULL for disabled vif right now) to the function in all current call sites.
