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