1ffa60ac01 Use macros from tcp_timer.h to manipulate TCP timers, so that their 
implementation can be changed easily.

334f006538 New TCP reassembly code. The new code reduces the memory needed by 
out-of-order packets and builds the infrastructure needed for sending
SACK blocks (to be added shortly).

fcf0227962 Fix to ensure that the correct MSS is advertised for loopback 
TCP connections by using the MTU of the interface.  Also added
a knob, mss_ifmtu, to force all connections to use the MTU of
the interface to calculate the advertised MSS.

e5e283e02d Finishing merging 4.4BSD-Lite2 netinet. At this point, the only changes 
left were SCCS IDs and Copyright dates.

2e85747e9e From 4.4BSD-Lite2 (noted by Frank van der Linden): 
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time.  However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere).  Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

ee84a26869 After further examination of traces of bulk transfers (with help from 
Kevin Lahey), undo the "defer window update until next delayed ACK".

c02a72fcd0 Implement an infrastructure to allow larger initial congestion windows. 
The sysctl'able variable "tcp_init_win", when set to 0, selects an
auto-tuning algorithm for selecting the initial window, based on transmit
segment size, per discussion in the IETF tcpimpl working group.

Default initial window is still 1 segment, but will soon become 2 segments,
per discussion in tcpimpl.

3026b32ab3 In the PRU_RCVD entry point, if TF_DELACK is set, don't send the window 
update now, since it will be sent within 200ms when the delayed ACK is
sent.  Instrument how many hits we get on this optimization.

8fb48a5db9 Eliminate a superflouus `if' statement: when detaching the TCP protocol from 
a socket, just calling tcp_disconnect() on the tcpcb will do the right thing.

49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and 
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.

* Convert several data structures to use queue.h.
* Split in_pcbnotify() into two parts; one for notifying a specific PCB, and
one for notifying all PCBs for a particular foreign address.
