us our first minimal glimpse of PowerPC support.
With this code we can get to the "mountroot>" prompt on my Apple iMac. We
can't get any further due to lack of clock and interrupt handling, among other
things. This does however mean that pmap and VM are initialising.
We're fairly dependant on OpenFirmware at this point, but I hope to add
support for other classes of firmware at a later stage.

Print type of pci bridge we find.
Force the IRQ of pci bridges upon all its children.
Allocate the resources on behalf of the bridge when we're testing to see if
they exist.
This should help people who don't read updating instructions very well.
This patch started out with an idea from Shigeru Yamamoto-san in -current.
make(1) wants to build loader.sym *before* the .o files. Eliminating
one seeminly intermediate step avoids the problem. Somehow, it seems
that variables are not getting expanded at the right time.
Any explanations would be appreciated...
Changing:
${BASE}.sym: ${OBJS} ${LIBSTAND} ${LIBFICL} ${LIBALPHA} ${CRT} vers.o
${LD} ...
To:
BASEOBJS= ${OBJS} ${LIBSTAND} ${LIBFICL} ${LIBALPHA} ${CRT} vers.o
${BASE}.sym: ${BASEOBJS}
echo ${BASEOBJS}
${LD} ...
.. the echo only shows LIBFICL, CRT and vers.o. ${OBJS} is not included.
told to use IRQ 6, progam the pcic to use irq 7 instead. Evidentally,
at least some of the cards are wired this way. If you want to use irq
6, configure it. All the mapping is done just before we set the
interrupt registers. See [FreeBSD98-testers 5064] for details.
Added commentary about valid interrupts on some CBUS pc98 CL PD6722
based cards.

know which). [FreeBSD98-testers 5098] contains all the details.

(I'll be we know which compiler and platform they developed this on...)
Minimally change them to C89 comments to make GCC happy. (this is kinda funny
as the file has piece derived from FreeBDS 3.2)
Also fix FreeBSD id style.
The DP83820/83821 has an undocumented limitation concerning jumbo frames
and TX checksum offload. In order for TX checksum offload to work, the
outgoing frame must fit entirely within the TX FIFO, which is 8192 bytes
in size. This isn't a problem, until you try to send a 9000-byte frame,
at which point the TX DMA engine goes to sleep. It turns out that if
you want to send a jumbo frame larger than 8170 bytes (8192 - 64), you
have to turn off the TX checksum support.
As a workaround, I changed nge_ioctl() so that if the user selects an
MTU larger than 8152 bytes, we clear the if_hwassist flags. The flags
will be set again once the MTU is reduced to a smaller value.
same as it did before the IPv6 commit. Probably irrelevent to freebsd,
but I think it was useful on other OS's. Also makes a few minor style chgs.

more sensible/understandable. 'from'->'from_host' 'host'->'local_host'
'fromb'->'frombuf' 'fromhost'->'origin_host' and a local-variable
named 'host'->'hostbuf'. This fixes some compile-time warnings about
local variables shadowing global variables.
Other than renaming variables, the only actual code changes are to call
strlcpy() instead of strncpy() when setting those (renamed) variables,
and that 'from_ip' is now a strdup()-created buffer instead of being a
static buffer compiled in as 1025 bytes.

- Use db_printf() instead of printf().
- Clean up decode_syscall() to use regular if-then-else rather than goto's.
- Use the same method of parsing PID's for per-process traces as the x86
code does: that is, if the address passed in is not a valid kernel
address, treat it is a decimal pid.
- If the pid of the current process is specified, fall back to using the
"default" parameters for the trace as curproc's pcb is not valid at this
point.

we want the checksums calculated on a per-packet basis using control bits
in the extsts field of the DMA descriptor structure. For TX, the chip
seems to want these bits set in the field of the first descriptor in
a fragment chain, not the last.
Removed the ambiguity in -s, -f, -p and -i flags handling.
Basically, there are four displays (except others):
1. PCB display.
2. Protocol statistics display. (-s)
3. Interface statistics display. (-i)
4. Per-interface protocol statistics display. (-i -s)
All of the above except 3) can be limited to a particular
protocol family (-f) or a single protocol (-p).
Some examples:
1. netstat -f inet -- show PCBs of all INET protocols
2. netstat -p udp -- show PCB of UDP protocol only (NEW!)
3. netstat -s -- show protocol statistics for all families
4. netstat -s -f inet -- show INET protocols statistics
5. netstat -s -p icmp -- show ICMP protocol statistics
This is a work in progress. Manpage has been fixed slightly,
but is still incomplete.
