Yes, the lack of a standardized management protocol is one of the NCM
shortcomings which were solved by MBIM (which started out as "NCM 2.0").

Good to hear :-)

It should at least allow us to try out a few things on the fly without
having to rebuild the driver.

One thing I forgot to mention is that you can completely disable the
padding in v3.16+ by setting "min_tx_pkt" >= "tx_max".  And these
settings can be changed while the modem is actively in use
(i.e. connected).
