* Makefile.am: Added sys/linker_set.h
* kern/Makefile.am: Added kern_mib.c and kern_sysctl.c.
* kern/uipc_socket.c: OID changed from KERN_SOMAXCONN to KIPC_SOMAXCONN.
* kern/uipc_socket2.c: OID changed from KERN_MAXSOCKBUF to
KIPC_MAXSOCKBUF.
* net/if_ethersubr.c: FreeBSD 2.2.2 does not have a _net_link node
while 5.0 does.
* net/if_ppp.c: Removed the TEXT_SET define as these macros are
now implemented.
* net/rtsock.c: Enable sysctl support plus fix the bug with the
lastest FreeBSD sysctl header file.
* netinet/icmp_var.h: FreeBSD 2.2.2 does not have a _net_inet_icmp
node while 5.0 does.
* netinet/if_ether.c: FreeBSD 2.2.2 does not have a _net_link_ether
node while 5.0 does.
* netinet/igmp_var.h: FreeBSD 2.2.2 does not have a _net_inet_igmp
node while 5.0 does.
* netinet/in_pcb.c: Fixed the arguments to the sysctl call. Add
inp_gencnt and ipi_count. These are used when listing connections.
* netinet/in_pcb.h: Added counters to aid the listing of connections.
* netinet/in_var.h: Provide the _net_inet_ip and _net_inet_raw nodes.
* netinet/ip_fw.c: Disable the firewall sysctl calls.
* netinet/tcp_subr.c: Merge tcp_pcblist from the lastest FreeBSD source.
* netinet/tcp_var.h: Add structures needed by net-snmp to list
connections.
* netinet/udp_usrreq.c: Merged udp_pcblist from the lastest FreeBSD
source.
* netinet/udp_var.h: Added the sysctl id UDPCTL_PCBLIST. Used by
net-snmp.
* rtems_glue.c: Call sysctl_register_all when initialising the
network stack to register all the sysctl calls. These are in the
special sections and required an updated linker script.
* rtems/rtems_syscall.c: Add the sysctl call.
* sys/kernel.h: Use the lastest FreeBSD method of handling sysctl
structures. This now held in the sys/linker_set.h file.
* sys/queue.h: This is from the lastest FreeBSD code with the circular
code merged back in as it is not used in the lastest FreeBSD kernel.
* sys/sysctl.h: The lastest sysctl. This was needed to use with the new
linker set method. The FreeBSD 2.2.2 version has asm hacks. The lastest
version of the FreeBSD does not have these hacks. It uses gcc attribute
directives.

that contains the automake files for libnetworking plus a couple of
minor fixes. [Now only one unused/unsupported Makefile.in remains
(./c/src/lib/libbsp/hppa1.1/pxfl/Makefile.in).]

* I have tested this one by building all BSPs for m68k, powerpc, sh and
unix with toolchains built since last weekend.
* I did not touch libnetworking's directory layout.
report from Philip A. Prindeville <philipp@zembu.com>:
I was working on a device driver for a certain ethernet chipset that
occassionally wraps in its buffer, and causes a resulting mbuf chain
with only a few dozen bytes in the first mbuf of the chain.
I wouldn't have thought this would be a problem, until I ran some
stress tests that flooded the ethernet receiver with packets and
started to get panics here:
250
251 if (m->m_pkthdr.len < sizeof(struct ip))
252 goto tooshort;
253
254 #ifdef DIAGNOSTIC
255 if (m->m_len < sizeof(struct ip))
256 panic("ipintr mbuf too short");
257 #endif
258
259 if (m->m_len < sizeof (struct ip) &&
260 (m = m_pullup(m, sizeof (struct ip))) == 0) {
261 ipstat.ips_toosmall++;
262 return;
263 }
264 ip = mtod(m, struct ip *);
and the panic was at line 256. But if I #undef'd DIAGNOSTICS,
then the m_pullup() at line 260 does the right thing and the packet
ends up being processed just fine.
So I started wondering, (a) why was the test checking for
something that apparently wasn't a fatal condition but rather
one that is subsequently recovered from a couple of lines later
and (b) why panic as a diagnostic "aid" from a recoverable
condition rather than just (say) log a message to the console?
All of this seems overly severe for no reason that is readily
apparent to me.
I've fixed a few minor probs with the optimised version that Eric put
together for me the other day and sent the fixes back to him. Provided he
doesn't have a problem with it we've got a pretty solid in_cksum for the
ColdFire as well as straight m68k. I've enclosed my updated in_cksum_m68k.c
At the moment my own bottlenecks are elsewhere...as my driver is pulling
16bit data chunks through a libchip-esq access routine from the chip which
for a polled I/O device is never going to be quick.
