a route. (This still doesn't work, but it doesn't panic now.) It looks
like there may be a number of incipient bugs in this code.
Also, get ready for the time when all IP gateway routes are cloning, which
is necessary to keep proper TCP statistics.
- Allow PPP to run multicasts natively.
- Deal properly with lots of similarly-named interfaces.
- Don't sign-extend if_flags.
NB: the last fix (to rtsock.c) must be reversed when we expand if_flags to a
reasonable size.
