Changes for 1.1.21

o       Small bug fix in the apricot xen-ii driver code (Mark Evans)
o       DE600 changes + DE620 driver (Bj0rn Eckwall)
o       WWW error return bug fixed (Everyone!)
o       SLIP default address is now better
o       Small changes to PLIP (Niibe)
o       Added PF_UNSPEC (Dominic Kubla)
o       TCP fastpath for receive.
o       Turbo charged tcp checksum routine (Arnt Gulbrandsen)
o       PPP locking bug fixes (Florian La Roche)

To Do

o       Include the HP onboard lance fixes.
o       Fix Unix domain sockets.
o       Fix the _SLOW_ TCP window calculation junk in tcp_data/tcp_ack.
o       Make the dev_add_proto() list hashed by protocol type.
o       Remove the call to dev->header_type - load it into the skbuff.
        instead to avoid the extra calls and cache misses.
o       Include new sk_buff skb_push() code and move toward using it.
o       Fix the PI driver so pi0a can be down when pi0b is up without getting
        crashes. Also fix the stuff to allow piconfig to set the parameters.
o       Make AX.25 set the packet type - certainly before it hits IP.
o       sk_buff building at the top level - pure kernel interfaces to the
        protocol layers
o       Clean up NFS, merge NFS/TCP code.
o       SIGIO
o       IP forwarding use of options properly (needs new sk_buff code)
o       Reroute TCP retransmits if needed (needs new sk_buffs)


Changes for 1.1.20

o       All read/write buffers are validated at the top level _only_
o       All address structures are moved to and from user mode at the top
        level. Thus you can now issue proto->bind(....) calls and related
        functions such as connect from another kernel task. All thats left
        to fix now is a kernel alloc_socket()/free_socket() and accompanying
        proto->make_kernel(socket)
o       Small fixes to address behaviour caused by the above
o       Max NFS size of 16K bytes
o       Added the apricot driver as a test (#'ed out in config.in)
o       Fixed a missing function definition in net_init.c
o       Added G4KLX ax25_router code
o       Added Niibe's PLIP driver and altered it to support timer
        configuration and IRQ/port setting. Added if_plip.h. Comments and
        feedback appreciated on this (both to Niibe and me).
o       Added AF_MAX/PF_MAX defines
o       Added a note that the DE600 driver also works for a noname 'PE1200'.
o       Network buffer statistics on shift-scroll_lock
o       Fixed a serious race in the device driver code. This was causing odd
        crashes with the Lance drivers, lockups with the ne2000 cards and
        a few other 'bad' goings on. All drivers are effected. See
        README.DEV if porting a driver to this revision.

        If you see entries in your 'free while locked' count, those would
        typically have crashed a pre 1.20 kernel.

o       TCP keeps the timers above 0.2sec round-trip time because of the use of
        delayed ACK's by BSD style kernels.
o       Fixed a small BSD error in the return from datagram socket
        recv/recvfrom() calls when data is truncated. BSD returns the true
        length of the message, Linux returned the amount copied which broke
        programs that did a MSG_PEEK with a small buffer and grew it if need
        be (some of the AV/RTP stuff notably).
o       Added TIOCINQ/OUTQ to AX.25 and IPX.
o       Added driver ioctl() calls to IPX.
o       Corrected the skb->len==0 in the tcp_data reset on shutdown to check
        skb->copied_seq.
o       IP options reflect onto SO_PRIORITY.
o       When a driver is downed its ARP entries are flushed. Should solve
        the occasional crash when taking out a modular driver.
o       Added Donald's multicast reception while promiscuous fix for the
        8390 drivers.
o       Potential ARP TCP-retransmit clear race fixed. Incredibly
        unlikely to occur but no doubt it will 8(.


Fixes added for 1.1.19

o       Unix domain bind error code.
o       skb->localroute starts cleared.
o       Compiles with networking disabled

Fixes added for 1.1.18

o       Dummy driver includes correctly.
o       PPP fixes from A.L.
o       ifslave fixes
o       Small error causing nfsd to coredump fixed by Linus.

Fixes added for 1.1.17

o       Charles Hedrick's fixes broken fragmentation totally. Mended.
o       Contributed 'dummy' device added. Apparently some slip people want it.
o       Tried to kill the memory problems with fragments by setting things
        up more carefully and guarding them.
o       Module fixes by Bj0rn.
o       PLIP fix by Tanabe.

Fixes added for 1.1.16

o       Charles Hedricks fixes to TCP.
o       Small fixes all over the place.

Fixes added for 1.1.15

o       Modular PLIP and 3c501 drivers. Now you -can- have multiple 3c501's
        (sort of).
o       Integrated new AX.25 - this will be ready for the big time in a few
        releases.

Fixes added for 1.1.14

o       Compiles properly on the whole 8)
o       Yet more Unix /proc protection.
o       Modular PLIP and 3c501 drivers. Now you -can- have multiple 3c501's
        (sort of).

This fixes the following from the 1.1.12 release (see the relevant files
for the credits to authors).

o       RARP compiles in properly
o       Using new Tytso TTY drivers
o       IP forwarding is configurable
o       PC/TCP support
o       AX.25 builds fine without SLIP driver (just PI)
o       MTU recognized in routing table (but only by TCP currently)
o       AX.25 PI driver merged into AX.25 code and kernel stubs
o       UNIX /proc trap hopefully fixed
o       DDI removed totally ready to use the PCMICA people's stuff
o       Unix domain lock/unlock now static (needlessly visible before)
o       Split net/inet/sock.c into generic and IP components
o       NFS client works correctly with 8K NFS
o       Non IP builds work correctly
o       Renamed inet_bh etc to net_bh to reflect true nature
o       TCP handling of poor routes much improved
o       TCP connect timing fixed
o       Incredibly unlikely SLIP memory leak removed
o       Loopback maintains IFF_LOOPBACK flag
o       Johnathon Naylor(G4KLX) AX.25 changes
o       Out of sync bug in lance driver fixed.
o       First cut at ethernet loadable modules
o       PCMICA people have ifmap stuff. Will extend this to other drivers.
o       New de600.c
o       Clean up of IP layer - sorted a lot of redundant and duplicated code
        out.
o       Removed all the old non working debugging junk from the kernel.
o       Removed all the devices the kernel used to use as a legacy from
        FvK's days writing the linux networking.
o       Greg Page's latest and greatest IPX fixes (including 802.2). Now
        I've got the stuff to write a free Netware client too and some
        volunteers to do it.
o       Fixed the 1.1.12 ARP fragment bug.
