This patch removes the setting of the ADC sampling bits in the mvm nic configuration. This setting is not required by the firmware, and furthermore - it interferes with the DBGC when it is running in DRAM mode on PCIe.

HW/FW constraints dictate that TDLS should only be used when a single phy ctx is active. We also support at most 4 TDLS peers. We don't support TDLS on a P2P vif. Unify and move a phy-ctx counting implementation from the power-mgmt code in order to simplify implementation.

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.

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.

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.

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.

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.
