  [Other Info]
   
   * Original description

  In bug 1962704, backport-iwlwifi-dkms of focal/impish/jammy is being
  proposed to upgrade to its revision 9580, but after v5.17 being
  released and entered Jammy as new -generic kernel, 9580 fails to build
  against the latest kernel headers due to multiple problems including
  API change in commit 7462494408cd ("ethtool: extend ringparam
  setting/getting API with rx_buf_len").

  This is fixed at least in upstream revision 9858
  (https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-
  iwlwifi.git/commit/?id=d0c7cb83a3772ed9dfb7b22242faea0951090ffd).
