net: usb: Add MUX support in embedded rmnet driver
Due to limited number of HSIC endpoints, to support
more than existing number of control and data channels,
driver needs to MUX all the data channels as well as
the control channels into one HSIC interface. MUX
support is enabled on PID 0x9075. MUX header is added
to IP/control packet based on the channel id while
transmitting to mdm device. Similarly, while receiving
driver removes and parses the MUX header and based on
channel id it forwards IP/control packet to appropriate
network interface/control channel.
