Title:
  RuntimeError: duplicate mac found! both 'wwan1' and 'wwan0'

Status in cloud-init:
  Fix Released

Bug description:
  Hi
  This bug is a variant of https://bugs.launchpad.net/cloud-init/+bug/1997922.

  I got this error only when PXE booting a target with a modem that has
  dual interface support, and using ubuntu-22.04.2-live-server-amd64.iso
  or ubuntu-22.04.1-live-server-amd64.iso. After a manual installation,
  the target boots fine without this error.

  Detected modems that cause this error:
  Quectel EG25
  Quectel RM510Q-GLHA
  Sierra Wireless MC7455

  Failure in cloud-init prevent automatic installation of targets in our
  production.

  Tested solution:
  After studying the info in bug 1997922, I downloaded https://github.com/canonical/cloud-init/blob/main/cloudinit/net/__init__.py and changed line 1043 to:
      if driver == "mscc_felix" or driver == "fsl_enetc" or driver == "qmi_wwan": 

  Then created a customized version of ubuntu-22.04.2-live-server-
  amd64.iso and tested in our production line, and now everything works
  fine.

  Logs:
  cat > get_driver.py <<EOF
  from cloudinit.net import device_driver
  import sys

  print(device_driver(sys.argv[1]))
  EOF

  for nic in wwan0 wwan1 eno1 eno2 eno3 eno4 eno5 eno6; do
   echo "----- $nic"
   ls -l /sys/class/net/$nic/
   python3 ./get_driver.py $nic;
  done
