Orange Pi5 kernel

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) Steve's quick list of things that need finishing off:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) [they are in no particular order and range from the trivial to the long winded]
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4)  o Proper timeouts on each neighbour (in routing mode) rather than
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5)    just the 60 second On-Ethernet cache value.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7)  o Support for X.25 linklayer
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9)  o Support for DDCMP link layer
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)  o The DDCMP device itself
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13)  o PPP support (rfc1762)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)  o Lots of testing with real applications
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)  o Verify errors etc. against POSIX 1003.1g (draft)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19)  o Using send/recvmsg() to get at connect/disconnect data (POSIX 1003.1g)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)    [maybe this should be done at socket level... the control data in the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)     send/recvmsg() calls should simply be a vector of set/getsockopt()
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22)     calls]
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24)  o check MSG_CTRUNC is set where it should be.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)  o Find all the commonality between DECnet and IPv4 routing code and extract
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27)    it into a small library of routines. [probably a project for 2.7.xx]
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29)  o Add perfect socket hashing - an idea suggested by Paul Koning. Currently
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)    we have a half-way house scheme which seems to work reasonably well, but
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)    the full scheme is still worth implementing, its not not top of my list
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32)    right now.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34)  o Add session control message flow control
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36)  o Add NSP message flow control
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38)  o DECnet sendpages() function
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40)  o AIO for DECnet
