    Add an implementation of GSM 0710 MUX. The implementation currently supports
    
    - Basic and advanced framing (as either end of the link)
    - UI or UIH data frames
    - Adaption layer 1-4 (1 and 2 via tty, 3 and 4 as skbuff lists)
    - Modem and control messages including the correct retry process
    - Flow control
    
    and exposes the MUX channels as a set of virtual tty devices including modem
    signals. This is an experimental driver.
