Bug description:
  Intel wireless driver and firmware require updates in order to meet
  the new ETSI regulation [1] for OEM machines shipped from factories.

  Intel provided us the following information for what are required to
  update:

  1. Kernel driver:

  https://patchwork.kernel.org/patch/10322121/
  https://patchwork.kernel.org/patch/10312731/
  https://patchwork.kernel.org/patch/10312735/
  https://patchwork.kernel.org/patch/10312733/

  - 7260, 7265, 7265D and 3168 NICs, 4.15 plus above driver patches
  - 8000 series requires 4.16.
  - 9000 series requires 4.17.

  2. linux-firmware
  Requires latest versions from linux-firmware.git

  3. wireless-regdb update

  [1]
  http://www.etsi.org/deliver/etsi_en/301800_301899/301893/02.01.01_60/en_301893v020101p.pdf

  -----------------------------------------------------------------------
  == SRU Justification for linux-firmware ==
  [Impact]
  Intel released these firmware updates to support the new ETSI 5GHz Adaptivity Requirement, OEM has to meet it in order to ship.

  [Test Case]
  Check dmesg to confirm the correct firmware is loaded, make sure the revision is correct, and check wifi can functions properly.

  [Regression Potential]
  It is possible that there is regression introduced by Intel's firmware, so should make sure wifi still works properly after the new firmware is used. We have verified the new firmwares of 7260 and 7265D on 4.4
  and 4.15 kernels. The 8000 and 9000 series firmwares have newer API versions and will need to confirm with subsequent driver changes.

  wireless-regdb SRU Justification

  Impact: New regulatory requirements in the EU necessitate updating our
  wireless regulatory database.

  Fix: New upstream release.

  Test Case: Minimal testing would be to reload the regdb (can be done
  with iw built from git or by rebooting) and verifying that you are
  able to change regulatory domains (e.g., sudo iw reg set US; iw reg
  get).

  Regression Potential: Minimal. Biggest risk would be the inability to
  load the new database due to the changes in signing, however testing
  will confirm that appropriate key is present.
