tty: n_gsm: add copyright Siemens Mobility GmbH
More than 1/3 of the n_gsm code has been contributed by us in the last
1.5 years, completing conformance with the standard and stabilizing the
driver:
- added UI (unnumbered information) frame support
- added PN (parameter negotiation) message handling and function support
- added optional keep-alive control link supervision via test messages
- added TIOCM_OUT1 and TIOCM_OUT2 to allow responder to operate as modem
- added TIOCMIWAIT support on virtual ttys
- added additional ioctls and parameters to configure the new functions
- added overall locking mechanism to avoid data race conditions
- added outgoing data flow to decouple physical from virtual tty handling
for better performance and to avoid dead-locks
- fixed advanced option mode implementation
- fixed convergence layer type 2 implementation
- fixed handling of CLD (multiplexer close down) messages
- fixed broken muxer close down procedure
- and many more bug fixes
With this most of our initial RFC has been implemented. It gives the driver
a quality boost unseen in the decade before.
