tty: n_gsm line discipline
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. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
