-2.	Verifying all the error returns match the BSD ones (grotty job I
-wouldn't wish on anyone).
-
-3.	'Fast Retransmit'. This is a TCP algorithm extension BSD uses. If
-you see about 3 acks in a row that are for the same 'old' value. You resend
-the frame following the ack. (The assumption being that the acks are
-because a single frame in the data stream has been lost). Given a 
-mathematician with some queue theory you can show this allows you to 
-lose one frame per window full of data without measurable speed loss.
-[done]
-
-4.	RFC1323. These are the extensions for very fast nets.
-RFC1323 will be useful for Linux talking to systems over 100 Mb/sec
-Ethernet and over ATM as it allows large windows and protects from some
-potential high speed TCP problems.
-[In progress]
-
-6.	Delayed ack. This is mostly supported but not actually set up and
-used yet. Basically ack frames are held back 1/10th of a second in the hope
-that two acks can be merged into one or for interactive use the ack can
-piggyback on the next character typed (great improvement on 2400 baud
-modems). Johannes Stille did some work on this about 0.99.13 but it never
-got merged in. [Pedro Roque] [Done, but needs fixing]
-
-7.	One on my tempting project list. Add an extra (unofficial - but so
-is SLIP6) SLIP mode that does packet data compression [maybe use the code
-from term].
-
 9.	Implementing streams. Not as a blind slow SYS5.4 style copy but actually
 working out how to do it so it runs like greased lightning. Quite a big
 problem. [See the LiS project]
 
-10.	Frame Relay/WAN/ISDN drivers [I'm working on the sonix EuroISDN board
-driver but that's for an internal project and its general release is still
-a maybe (so is finishing it ;))][Jim Freeman is working on Frame Relay as is
-Mike McLagan][Fritz Elfert is doing the isdn4linux kit].
- 
 11.	IP over SCSI. [worked on]
 
 14.	Bidirectional PLIP. Also PLIP for the newer style parallel ports.
@@ -449,22 +29,13 @@
 rumour is microsoft are phasing out netbeui for netbios/IP. Microsoft have
 gone for netbios/funny-ipx-variant it seems in Win95, but TCP is selectable.
 
-16.	X.25. This is one for a real head case with far too much time on

 17.	PPP multilink. Another nasty job.
-[In progress]

 19.	IPv4 IP-AH and IP-ESP.

 BTW: Don't let the magic words 'kernel programming' worry you. Its like DOS
