The mvm op_mode won't allocate the buffer for the transport any more. The transport allocates its own buffer and mvm is in charge of splicing the buffers in the debugfs hook. This makes the repartition easier to handle. Reviewed-by:

The recent unified scan api change introduced issues when stopping ongoing scans, since both regular and sched scan now use same stopped notification. When issuing a new scan right after a running one, we get the "old" notification and handle it wrongly as notification for the current scan. Fix it by introducing a new function that make sure we consume the pending notifications before issuing a new scan. Signed-off-by:

According to new requirements, the ACK / CTS kill mask is not related to reduced TX power anymore. This allows to remove the code that tracked reduced TX power enablement across different interfaces. The ACK / CTS kill mask is now fetch from a table. It depends on the Activity grading (activity from BT) and on the Look Up Table (LUT) type. Signed-off-by: -

The Remain On Channel framework added to the firmare is a bit like time events. It allows the driver to request the firmware to be on a certain channel for a certain time. Unlike the time events, the ROC infrastructure doesn't need a MAC context in the firmware - it uses a generic context called "auxiliary framework". This is useful for any offchannel activity that is not bound to a specific MAC. The flow is synchronized much like with time events: 1) The driver receives an action frame from the wpa_supplicant via nl80211 that requests to be sent offchannel. 2) The driver sends an Aux ROC command (0x53) to the firmware. 3) The firmware responds with the unique id of the time event. 4) When time event starts, the driver puts the frame in the Aux queue. Special care needs to be taken when the time events ends: the queue needs to be cleaned-up. Signed-off-by:

Add new AUX ROC command that is intended for HS2.0 purposes. It is used to send ANQP requests on a specific channel. This command requests the firmware to trigger a time event and remain on a certain channel for a given duration. Triggering the time event is done by using the Aux Framework in the firmware, and makes use of the Aux station (similarly to scan). Signed-off-by:

Add iwl_mvm_ref_sync() calls (with new ref types) to flows that might access the device directly. These calls make sure the device is out of d0i3, and the bus is available for direct access. Since some of these functions are reentrant, convert the refs_bitmap to a ref counter, so multiple refs of the same type could be taken concurrently. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

There are some cases where we can currently send zero quota for a valid binding, e.g. if we update while an interface is bound to a channel context but not yet acting as an AP. Avoid this by reordering the checks. Signed-off-by:

In some cases (e.g. when we're doing a channel switch), we may need to disable the quota of a vif temporarily. In order to do so, add an argument to the iwl_mvm_update_quotas() function to tell if the passed vif is a new one or if it should be disregarded. Signed-off-by:

iwl_mvm_rs_rate_init() is called multiple times to re-init the rate scaling statistics (e.g. after some idle time). It clears all the lq_sta sta, including some fields that shouldn't be cleared (e.g. debugfs pointers). Fix it by adding a new 'persistent' sub-struct, and avoid clearing it on (re-)init. Move the initialization of the persistent fields to rs_alloc_sta instead. Signed-off-by:
