====================
wireless fixes for v5.18

Second set of fixes for v5.18 and hopefully the last one. We have a
new iwlwifi maintainer, a fix to rfkill ioctl interface and important
fixes to both stack and two drivers.

  rfkill: uapi: fix RFKILL_IOCTL_MAX_SIZE ioctl request definition
  nl80211: fix locking in nl80211_set_tx_bitrate_mask()
  mac80211_hwsim: call ieee80211_tx_prepare_skb under RCU protection
  mac80211_hwsim: fix RCU protected chanctx access
  mailmap: update Kalle Valo's email
  mac80211: Reset MBSSID parameters upon connection
  cfg80211: retrieve S1G operating channel number
  nl80211: validate S1G channel width
  mac80211: fix rx reordering with non explicit / psmp ack policy
  ath11k: reduce the wait time of 11d scan and hw scan while add interface
