All speeds between 1 and LONG_MAX are valid.  Some drivers support
setting speeds that can't be handled by tty_compat.  E.g., the cy
driver allows 76800 and 150000 and many others.  Handling these
is a problem for tty_compat and crufty applications, not for the
termios driver.

All h/w tty drivers (except iitty :-() do their own speed checking.
Perhaps the pty driver should only allow the standard speeds.
