I just wait for someone to review it, it works fine for EM7305. But now
the Dell project want support another new device(EM7445), I just add
some other new patches, but currently it  can't work, and I need more
time to debug it. :)

 I just prepare to backport below two patches, now it could build and
run successfully. But they can't work for MBIM device, cause the
backport depends on a lot changes, might be missed some other code.

    sierra: move all the legacy Sierra support to a new 'sierra-legacy'
plugin

    In short:

      * The 'sierra-legacy' plugin will handle all the old AT based modems,
        including the DirectIP ones. This plugin is filtered by driver ('sierra' or
        'sierra_net') and forbidden-drivers ('qmi_wwan' and 'cdc_mbim'). This plugin
        should also grab HP and AT&T branded models if they are handled by the
        proper kernel driver.

      * The 'sierra' plugin will only handle QMI or MBIM based Sierra modems, which
        are really all the new ones. This plugin is filtered by VID (0x1199) and
        driver (qmi_wwan and cdc_mbim).

    For this separation to work, the 'sierra' and 'sierra_net' plugins need to be
    complementary to each other.

Title:
  novatel: improve probing for Dell branded modems

Bug description:
  Dell rebrands modems from different vendors, including Novatel, Sierra
  and Ericsson. Until now we defaulted to the Novatel plugin when a Dell
  device was found, but then we're breaking newer MBIM Sierra Dell-
  branded modems, as we don't have MBIM support in the Novatel plugin.

  So, we should try to improve the probing in the Novatel, Sierra and
  MBM plugins, so that they probe also Dell devices, and we'll then try
  to match via AT-probing which plugin should be handling the Dell
  device.

  Could we backport this patch  into trusty? Thanks!
