wireless-next patches for v6.11

Browse Source 
Most likely the last "new features" pull request for v6.11 with
 changes both in stack and in drivers. The big thing is the multiple
 radios for wiphy feature which makes it possible to better advertise
 radio capabilities to user space. mt76 enabled MLO and iwlwifi
 re-enabled MLO, ath12k and rtw89 Wi-Fi 6 devices got WoWLAN support.
 
 Major changes:
 
 cfg80211/mac80211
 
 * remove DEAUTH_NEED_MGD_TX_PREP flag
 
 * multiple radios per wiphy support
 
 mac80211_hwsim
 
 * multi-radio wiphy support
 
 ath12k
 
 * DebugFS support for datapath statistics
 
 * WCN7850: support for WoW (Wake on WLAN)
 
 * WCN7850: device-tree bindings
 
 ath11k
 
 * QCA6390: device-tree bindings
 
 iwlwifi
 
 * mvm: re-enable Multi-Link Operation (MLO)
 
 * aggregation (A-MSDU) optimisations
 
 rtw89
 
 * preparation for RTL8852BE-VT support
 
 * WoWLAN support for WiFi 6 chips
 
 * 36-bit PCI DMA support
 
 mt76
 
 * mt7925 Multi-Link Operation (MLO) support

/**
* DOC: target -> host extended statistics upload
*
* The following field definitions describe the format of the HTT
* target to host stats upload confirmation message.
* The message contains a cookie echoed from the HTT host->target stats
* upload request, which identifies which request the confirmation is
* for, and a single stats can span over multiple HTT stats indication
* due to the HTT message size limitation so every HTT ext stats
* indication will have tag-length-value stats information elements.
* The tag-length header for each HTT stats IND message also includes a
* status field, to indicate whether the request for the stat type in
* question was fully met, partially met, unable to be met, or invalid
* (if the stat type in question is disabled in the target).
* A Done bit 1's indicate the end of the of stats info elements.
*
*
* |31 16|15 12|11|10 8|7 5|4 0|

* | stats entry length | rsvd | D| S | stat type |
* |--------------------------------------------------------------|
* | type-specific stats info |
* | (see debugfs_htt_stats.h) |
* |--------------------------------------------------------------|
* Header fields:
* - MSG_TYPE
* Bits 7:0
* Purpose: Identifies this is a extended statistics upload confirmation
* message.
* Value: 0x1c
* - COOKIE_LSBS
* Bits 31:0
* Purpose: Provide a mechanism to match a target->host stats confirmation
* message with its preceding host->target stats request message.
* Value: MSBs of the opaque cookie specified by the host-side requestor
* - COOKIE_MSBS
* Bits 31:0
* Purpose: Provide a mechanism to match a target->host stats confirmation
* message with its preceding host->target stats request message.
* Value: MSBs of the opaque cookie specified by the host-side requestor
*
* Stats Information Element tag-length header fields:
* - STAT_TYPE
* Bits 7:0
* Purpose: identifies the type of statistics info held in the
* following information element
* Value: ath12k_dbg_htt_ext_stats_type
* - STATUS
* Bits 10:8
* Purpose: indicate whether the requested stats are present
* Value:
* 0 -> The requested stats have been delivered in full
* 1 -> The requested stats have been delivered in part
* 2 -> The requested stats could not be delivered (error case)
* 3 -> The requested stat type is either not recognized (invalid)
* - DONE
* Bits 11
* Purpose:
* Indicates the completion of the stats entry, this will be the last
* stats conf HTT segment for the requested stats type.
* Value:
* 0 -> the stats retrieval is ongoing
* 1 -> the stats retrieval is complete
* - LENGTH
* Bits 31:16
* Purpose: indicate the stats information size
* Value: This field specifies the number of bytes of stats information
* that follows the element tag-length header.
* It is expected but not required that this length is a multiple of
* 4 bytes.
