Can you guys take a look at the 'aleksander/session-support' branch? The
changes in the branch allow to have MBIM 'sessions', using --no-close
and --no-open, while keeping the transaction ID between mbimcli
commands. I updated the mbim-network script accordingly as well.

E.g.:

    Open device:
      $> sudo mbimcli -d /dev/cdc-wdm0 --noop --no-close
      [/dev/cdc-wdm1] Session not closed:
            TRID: '2'

    Run a command:
      $> sudo mbimcli -d /dev/cdc-wdm1 \
                      --query-radio-state \
                      --no-open=2 \
                      --no-close
      [/dev/cdc-wdm1] Radio state retrieved:
             Hardware Radio State: 'on'
             Software Radio State: 'on'
      [/dev/cdc-wdm1] Session not closed:
            TRID: '3'

    Close device:
      $> sudo mbimcli -d /dev/cdc-wdm0 --noop --no-open=3
