Modes

From Juul on Github:

MBIM is just the NCM protocol + a signalling channel and QMI is just the ECM protocol + a signalling channel.

ECM is the Ethernet Control Model and NCM is the Network Control Model. ECM is an earlier standard and has some issues with latency while NCM resolves those issues and is designed for high speed operation.
