  # 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/

  # 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: 
    - the code /driver/net/usb/cdc_mbim.c is the same between xenial kernel 
4.4.0 and yakkety kernel 4.8.0.
