The modem modules cmux module is currently directly coupled to the presence of specific modems, rather than being selected by drivers for whatever hardware wants to request the default MTU of 127 bytes. This commit the makes the device drivers (for now, modem_cellular) select the symbol, thus decoupling the modem modules from the presence of any specific device.

This driver uses the generic 3gpp AT commands, along
|
|
with the standard protocols CMUX and PPP, to configure
|
|
cellular modems to establish a point-to-point
|
|
network connection. It is a template for tailored
|
|
drivers for the ublox, quectel and other modems, which
|
|
include power management and more complex device specific
|
|
features.
