|
* Intel Mobile Communication modem protocol driver for DLP
|
|
* (Data Link Protocl (LTE)).
|
|
* This driver is implementing a 5-channel HSI protocol consisting of:
|
|
* - An internal communication control channel;
|
|
* - A multiplexed channel exporting a TTY interface;
|
|
* - Three dedicated high speed channels exporting each a network interface.
|
|
* All channels are using fixed-length pdus, although of different sizes.
