====================
wireless-next patches for v6.11

The first "new features" pull request for v6.11 with changes both in
stack and in drivers. Nothing out of ordinary, except that we have
two conflicts this time:

net/mac80211/cfg.c
  https://lore.kernel.org/all/20240531124415.05b25e7a@canb.auug.org.au

drivers/net/wireless/microchip/wilc1000/netdev.c
  https://lore.kernel.org/all/20240603110023.23572803@canb.auug.org.au

Major changes:

cfg80211/mac80211
 * parse Transmit Power Envelope (TPE) data in mac80211 instead of in drivers

wilc1000
 * read MAC address during probe to make it visible to user space

iwlwifi
 * bump FW API to 91 for BZ/SC devices
 * report 64-bit radiotap timestamp
 * enable P2P low latency by default
 * handle Transmit Power Envelope (TPE) advertised by AP
 * start using guard()

rtlwifi
 * RTL8192DU support

ath12k
 * remove unsupported tx monitor handling
 * channel 2 in 6 GHz band support
 * Spatial Multiplexing Power Save (SMPS) in 6 GHz band support
 * multiple BSSID (MBSSID) and Enhanced Multi-BSSID Advertisements (EMA)
   support
 * dynamic VLAN support
 * add panic handler for resetting the firmware state

ath10k
 * add qcom,no-msa-ready-indicator Device Tree property
 * LED support for various chipsets
