64-bit changes -- ioctl cmds are u_longs.

4.4BSD snapshot (revision 8.1); add 1993 to copyright

trailing comment after #else or #endif

make kernel includes standard

make compile under both new and old vm system

new copyright notice

new convention for who frees ancillary data

access rights special case of ancillary data

get rid of unneeded include files

changes for var. length sockaddrs, routing lookup changes,
checkpoint at first working tp4 connection, before gnodes

checkpoint version with mbuf changes before var sockaddrs

install approved copyright notice

in attach, don't set sockbuf limits if set (from sonewconn); lint

we get our own copy of xxx_timer.h (I don't want to debug TCP and SPP
simultaneously!)

Three bug fixes from/with torek: dupacks check was one off;
ssthresh was not scaled; the code to remove multiple acked packets was wrong;
also some minor de-linting.

Change licensing/use notice.

This incorporates recent tcp strategies of Karels/Jacobson:
slow start, clamped rxmt, binary fixed point rtt smoothing. Works on sun 3.X

need systm.h for insque

4.3BSD release version

if request to send oobd denied don't free mbuf twice;
Be careful to calculate free space using signed arithmetic.

1.) If not using delayed acks, must still ack packets which are
otherwise dropped as duplicates.
2.) Kernel should return error on illegal socket option requests.
(or pass them further down the layer

Bug in deciding to retransmit a packet.

Fix retransmisssion, out of band bugs.

1. when raising windows, let those frozen out know
2. allow an option for two way shakes instead of three way shakes on open
3. clear OOB indications, but not on peeks
4. make sure that when calculating windows it does so with signed arith.

Pay lip service to interface tracing, ctlinput now expects
sockaddrs in response to imp stuff, add option for larger mtu's (default
is now and was supposed to be 576 bytes).
