new stats; change keepalives to use rcv_nxt instead of rcv_nxt-1
with no data (so we won't ignore the resets)

4.3BSD release version

fix up FIN_WAIT_2 timeout: don't send keepalives, as the reset
won't be received, but will reset idle time; don't reset idle time unless
packet received

rename tcp compat so can use separately

readjust timer values so rerouting on connection attempt
happens before timeout

ifdefs for 4.2 compat

faster backoff: multiply by beta, increase backoff (nearer exponential),
convert to int

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

more retransmits (wait longer than routed!); close FIN_WAIT_2's
if user has closed and is inactive; fix comments

Add copyright

don't cancel round-trip timer on REXMT until 1 successful measurement

reallocate route if losing

don't loop in slowtimo if inpcb has no tcpcb

fix round-trip timing: rexmt timer shouldn't screw rtt up,
but careful when retransmitting timed segment
