Title:
  USB tethered Xiaomi Poco X3 no longer recognized as eth0 device

Status in linux-hwe-6.11 package in Ubuntu:
  Confirmed

Bug description:
  After upgrading from kernel version 6.11.0-26-generic to
  6.11.0-29-generic, plugging my Xiaomi Poco X3 phone (LineageOS 21 /
  Android 14) to Ubuntu with USB tethering enabled doesn't show the
  connection in NetworkManager, and the device appears as type wwan
  (unmanaged by NetworkManager), and doesn't get an IPv4 address, so it
  cannot be used as a wired network device.

  System reboots:

  reboot   system boot  6.11.0-29-generi Fri Jul 11 09:04 - 18:03  (08:58)
  reboot   system boot  6.11.0-26-generi Mon Jul  7 08:06 - 02:02 (3+17:55)

  Ubuntu version

  No LSB modules are available.
  Description:  Ubuntu 24.04.2 LTS
  Release:      24.04

  A possible workaround is

  
  $ sudo tee /etc/systemd/network/99-usb.network > /dev/null <<EOF
  [Match]
  Driver=rndis_host

  [Network]
  DHCP=yes
  EOF

  Then

  $ sudo systemctl enable --now systemd-networkd
  $ sudo systemctl restart systemd-networkd

  Then the network be available (although still not visible in
  NetworkManager).
