[Antoine Lassagne <2117497@xxxxxxxxxxxxxxxxxx>]

An additional information I just got from our partner. They claim that
any computer that advertise Wifi 7 compatibility in China must
demonstrate that Multi Link Operation works. This is part of the SRRC
(State Radio Regulatory Commission) certification. This is one of the
reason why the OEMs are asking for this.

I know these arguments are not making this SRU any less risky, and the
risk is the real priority. But everyone is probably curious about the
context.

Title:
  No Wifi 7 MLO support

Status in wpa package in Ubuntu:
  Fix Released
Status in wpa source package in Noble:
  New
Status in wpa source package in Plucky:
  New
Status in wpa source package in Questing:
  Fix Released

Bug description:
  SRU Justification:

  [ Impact ]

   * This is a hardware-enablement SRU

   * Recent wifi modules are compatible with wifi 7 that comes with a
  bunch of cool features like Multi-Link Operation (MLO) which speeds up
  wifi. The kernel is compatible with these since 24.04 (Noble)

   * wpa 2.11 is required for these features to be available. it's
  available in Questing already. The release note is here:
  https://lists.infradead.org/pipermail/hostap/2024-July/042847.html

   * There were 2295 commits from 2.10 to 2.11. During these, the wifi 7
  support and reliability was gradually improved. It feels much safer to
  backport the version from Questing entirely compared to cherry-picking
  patches.

   * The 2.11 version landed in Questing a bit more than a month ago,
  which gave time for this new version to be tested by all questing
  users.

  [ Fix ]

   * The proposed fix consists in backporting the version from questing,
  entirely.

  [ Test Plan ]

   1. Run the Wireless Network certification suite from Checkbox, that will
      * Connect and disconnect to all kind of wifi
      * Scan the network

      wireless/wireless_scanning_interface
      wireless/wireless_connection_wpa_bg_nm_interface
      wireless/wireless_connection_open_bg_nm_interface
      wireless/wireless_connection_wpa_n_nm_interface
      wireless/wireless_connection_open_n_nm_interface
      wireless/wireless_connection_wpa_ac_nm_interface
      wireless/wireless_connection_open_ac_nm_interface
      wireless/wireless_connection_wpa_ax_nm_interface
      wireless/wireless_connection_wpa3_ax_nm_interface
      wireless/wireless_connection_open_ax_nm_interface
      wireless/wireless_connection_wpa_be_nm_interface
      wireless/wireless_connection_wpa3_be_nm_interface
      wireless/wireless_connection_open_be_nm_interface

   2. Run the Multi-link operation test suite from Checkbox, that will
  test the compatibility with MLO

      wireless/wifi7_mlo_interface

   3. My test plan involves having 5 persons using this daily for a week
  (at least on Noble). I'd like to have a diverse set of routers and
  machines involved. The testers will be asked to be more aware than
  usual about wifi disconnections, and reliability. I'll ask them to run
  bandwith test every morning with both the proposed package and the
  original one.

  [ Where problems could occur ]

   * Given the size of the update, any wifi-related issue could happen.
   * The test plan tries to cover as much wifi usage as possible to reflect this.

  [ Other Info ]

   * I've been using wpa 2.11 on my side for a month, on Noble. No issue
  there, but I don't have a wifi 7 router.

  This issue is about bumping the version Ubuntu. Debian is not up-to-
  date, yet.
