Some of these changes are a bit rough and will become
more polished later. the changes to if_ethersubr should largely be moved
to within the appletalk code, but that will happen later.
A few of these were related to network-byteorder problems,
and more were related to loopback failures.
Distribute all but the most fundamental malloc types. This time I also
remembered the trick to making things static: Put "static" in front of
them.
A couple of finer points by: bde
Introduce the SIOC[SG]IFGENERIC hooks that can be used to pass an
arbritrary ioctl subcommand into an interface driver. Surprisingly
enough, there was no provision for this already present (except of the
option of abusing SIOC[SG]IFMEDIA for this).
The idea is that an interface driver can establish ioctl subcommands
of its own that can't be meaningfully interpreted by the upper layer
interface ioctl function. Something like this is required to
implement a clean solution of passing down things like CHAP secrets or
PPP options to the /sys/net/if_sppp* files. (Yes, my CHAP is now
finally working with it, but i gotta update my kernel to the new
callout interface before being able to commit _that_.)

by a protocol, to detirmine if an address matches the net this address
is part of. This is needed by protocols for which netmasks
"just don't work", for example appletalk.
Also add the code in appletalk to make use of this new feature.
Thsi fixes one of the longest standing bugs in appletalk.
The inability to talk to machines to which the path is via a router
which is on a different net, but the same netrange, as your interface.
Protocols that do not supply this function (e.g. IP) should not be affected.
2.3.0 -> 2.3.1 changes, but I seem to recall that there are certain
"issues" with 2.3.1 (I'm not sure if it's just pppd or the whole lot, I
am not quite that far). The present pppd seems to work with it just fine
for the time being.
Among the changes are that zlib (aka LZ77 aka deflate aka gzip) compression
is implemented as well as the original compress(1) LZW style.
socket addresses in mbufs. (Socket buffers are the one exception.) A number
of kernel APIs needed to get fixed in order to make this happen. Also,
fix three protocol families which kept PCBs in mbufs to not malloc them
instead. Delete some old compatibility cruft while we're at it, and add
some new routines in the in_cksum family.
returning ICMP_TIMXCEED)
use CISCO_UNICAST instead of CISCO_MULTICAST to send normal packets.
this is needed for packets to get processed by a cisco router,
but doesn't matter if a packet is just forwarded.

than max_failures attempts, we are going to REJ it, to prevent endless
NAK loops.
(This is actually part of a larger local set of modifications i'm
running with, but the remainder (PAP & CHAP) ain't ready for prime-
time yet.)
1/ is compatible with the old route(1) in case needed.
2/ actually fixes the problem while vetting bad user input.
note: I have already fixed route(1) so the problem shouldn't occur.
if it does. use 0.0.0.0/0 instead of the word 'default' :)
We need to accept at least one sockaddr with zero length, in order
to be able to set the default route.
Suggested by: Phone conversation with Julian (sleep well!)
Route(1) has a bug that sends a bad message to the kernel. The kernel
trusts it and crashes. Add some sanity checks so that
we don't trust the user quite as much any more.
