[Bug 1693756] Re: [Xenial][ DW5816e] to support qmi over mbim which needed for FCC authentication.

[Alex Tu]

refer to versioning rule of libtool[1], there are some versioning changes added.
And this version is the candidate to be took into oem image.
The candidate binary packages could also be found in this ppa[1]

So, sum things up here again:

[The changes packages and it's .so version]
libmbim-glib4_1.12.2-2ubuntu1_amd64.deb ->
libmbim-glib4_1.12.2-2ubuntu1oem2_amd64.deb
 * libmbim-glib.so.4.1.0 - > libmbim-glib.so.4.1.1

libmbim-proxy_1.12.2-2ubuntu1_amd64.deb ->
libmbim-proxy_1.12.2-2ubuntu1oem2_amd64.deb

libqmi-glib1_1.12.6-1_amd64.deb -> 
libqmi-glib1_1.12.6-1oem1_amd64.deb
 * libqmi-glib.so.1.3.0 -> libqmi-glib.so.1.4.0

libqmi-proxy_1.12.6-1_amd64.deb -> 
libqmi-proxy_1.12.6-1oem1_amd64.deb

libmm-glib0_1.4.12-1ubuntu1_amd64.deb -> 
libmm-glib0_1.4.12-1ubuntu1oem2_amd64.deb
 * libmm-glib.so.0.2.0 -> libmm-glib.so.0.2.0

modemmanager_1.4.12-1ubuntu1_amd64.deb ->

Title:
  [Xenial][ DW5816e] to support qmi over mbim which needed for FCC
  authentication.

Status in OEM Priority Project:
  In Progress
Status in modemmanager package in Ubuntu:
  New

Bug description:
  # issue:
   * wwan card DW5816e[413c:81cc] couldn't be recognized by modemmanager 1.4.12-1ubuntu1 on xenial.
    - but works well on on Yakkety.

  # investgation:
   * in failed case, mmcli -L shows nothing on Xenial with DW5816. Then tried install followed packages from Yakkety ppa on Xenial and wwan card works on 1st boot but failed after 2nd boot sometimes.
    - libmbim-glib4_1.14.0-1_amd64.deb
    - libmbim-glib-dev_1.14.0-1_amd64.deb
    - libmbim-proxy_1.14.0-1_amd64.deb
    - libmbim-utils_1.14.0-1_amd64.deb
    - libqmi-glib5_1.16.0-1_amd64.deb
    - libqmi-proxy_1.16.0-1_amd64.deb

   * different from ModemManager --debug
     - In passed case, it received message from /dev/cdc-wdm1 after send "Read max control message size from descriptors file: 4096" , but not happens to failed case. So, it prints "[mm-port-probe.c:261] mm_port_probe_set_result_qcdm(): (tty/ttyS4) port is not QCDM-capable" in failed case.
       - passed case: http://paste.ubuntu.com/24664908/
       - failed case: http://paste.ubuntu.com/24664910/

  # Plan:
   * let the newer version packages could also works well on Xenial.
   * find out needed patches on newer version packages.
   * packport needed patches to older version packages on Xenial.

  # environment information:

   * modinfo cdc_mbim for original kernel module: http://paste.ubuntu.com/24662359/
    - the code /driver/net/usb/cdc_mbim.c is the same between xenial kernel 4.4.0 and yakkety kernel 4.8.0.

   * uname -r: 4.4.0-73-generic

   * lsusb -v: http://paste.ubuntu.com/24662332/
