Merge tag 'net-6.17-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from netfilter, wireless and Bluetooth.

  We're reverting the removal of a Sundance driver, a user has appeared.
  This makes the PR rather large in terms of LoC.

  There's a conspicuous absence of real, user-reported 6.17 issues.
  Slightly worried that the summer distracted people from testing.

  Previous releases - regressions:

   - ax25: properly unshare skbs in ax25_kiss_rcv()

       - mt7921: don't disconnect when AP requests switch to a channel
         which requires radar detection
       - mt7925u: use connac3 tx aggr check in tx complete

   - wifi: intel:
       - improve validation of ACPI DSM data
       - cfg: restore some 1000 series configs

   - wifi: ath:
       - ath11k: a fix for GTK rekeying
       - ath12k: a missed WiFi7 capability (multi-link EMLSR)
