Will modem inhibition truly release MBIM port ?

[Edward Chang]

Hi Aleksander,
                       The log with the latest libmbim is attached.
And, Yes, we created 3 messages "Update Session", "File Open", and "File
Write" which you may see from the log.
 The fragmentation which we do (not in libmbim) is to divide the firmware
image with MaxTransferSize(262144 bytes in the log) which is the maximum
amount of file data, that the function can receive in a single CID
transaction. Libmbim itself will sub-divide the fragment with the "max
control transfer" size( here 4096 bytes).
