Title:
  ModemManager uses a wrong plugin for Dell DW5818/5819

Status in modemmanager package in Ubuntu:
  New

Bug description:
  Since linux-4.4.0-98, the kernel additionally load gcserial driver for
  Dell Wireless DW5818/5819. The reason behind it is to support firmware
  switching and upgrading. However, the change makes ModemManager to use
  Gobi plugin for this two modules. With Gobi plugin, the modules could
  establish data links, but it failed to retrieve the signal state. And
  it caused the mmcli and nm-applet giving wrong signal strength. The
  modules support the MBIM protocol, so ModemManager should use Dell
  plugin for these two modules.

  I have worked out a patch to forbid these two modules in Gobi plugin,
  and it does work well.
