1Steve's quick list of things that need finishing off:
2[they are in no particular order and range from the trivial to the long winded]
3
4 o Proper timeouts on each neighbour (in routing mode) rather than
5   just the 60 second On-Ethernet cache value.
6
7 o Support for X.25 linklayer
8
9 o Support for DDCMP link layer
10
11 o The DDCMP device itself
12
13 o PPP support (rfc1762)
14
15 o Lots of testing with real applications
16
17 o Verify errors etc. against POSIX 1003.1g (draft)
18
19 o Using send/recvmsg() to get at connect/disconnect data (POSIX 1003.1g) 
20   [maybe this should be done at socket level... the control data in the
21    send/recvmsg() calls should simply be a vector of set/getsockopt()
22    calls]
23
24 o check MSG_CTRUNC is set where it should be.
25
26 o Find all the commonality between DECnet and IPv4 routing code and extract 
27   it into a small library of routines. [probably a project for 2.7.xx]
28
29 o Add perfect socket hashing - an idea suggested by Paul Koning. Currently
30   we have a half-way house scheme which seems to work reasonably well, but
31   the full scheme is still worth implementing, its not not top of my list
32   right now.
33
34 o Add session control message flow control
35
36 o Add NSP message flow control
37
38 o DECnet sendpages() function
39
40 o AIO for DECnet
