use Berkeley specific header

remove redundant assignments

useless register declarations

once again, try to get local address right: this time for DONTROUTE
on point-to-point links (need to zero sin_port before calling ifa_ifwithdstaddr

rewrote too much last time... use ifp even if old route was good

4.3BSD release version

watch for DONTROUTE when choosing local address

don't bother checking whether local on connect,
just use routing; if interface route was changed, want to use other IF.

lint

lint

don't use direct interface address if it's down

minor cleanups

reserve a port range for unprivileged servers

change tcp notification of transmission problems so that ip
can delete routes created by redirect that have gone bad

free ip options when detaching; notify routine to in_pcbnotify
is now optional; lint; zap a goto

Add copyright

more fixes

move net addresses from interface to protocol layer

from Jim McKie

generalize in_pcbnotify, use it to cause reallocation of routes
after receipt of a redirect

bind local address according to routing (caching the route);
pick maximum seg sizes (offered and accepted) based on interface mtu,
with default if not local

Include file changes. No more ../h

4.2 distribution

from wnj; auto-anchor local port on connect
