in VMware reports 0x00000000 in the PCI subsystem ID register, but
0x10001000 when you read the mirror registers in I/O space. This causes
pcn_probe() to think it's found a card in 32-bit mode, and performing
a 32-bit I/O access makes on a 16-bit port makes VMware go boom. Special
case the 0x10001000 value until somebody at VMware grows a clue.

For TCP, verify that the sequence number in the ICMP packet falls within
the tcp receive window before performing any actions indicated by the
icmp packet.
Clean up some layering violations (access to tcp internals from in_pcb)
handle read and write requests for widths of multiple bytes. This
can be used to read 16-bit battery status registers for example.
- Remove some unused variables and #if 0'd debugging cruft.
- Don't complain about a GPE query that fails due to AE_NOT_FOUND if the
query method was _Q00.
from a BIF, use the size of the destinatino buffer, not the length of the
string to determine where to put the nul char. As a side effect, the
old code would truncate the string by one character while it was possibly
overflowing the buffer.
This piece of code has not been referenced since it was put there
in 1995. Also done a codebased search on popular networking libraries
and third-party applications. This is an orphan.

o Allocate memory mapped by pcic even when not used for ncv.
This is for PC-Cards which needs offset, because I/O space should not be
used by other devices.

Incredibally useful for debugging kernels using vmware.
Vmware com1 is diverted to one side, and gdb listens to the other side.
viola.. instant debugging sandbox on one system.
Since we know there's always an upper bound we force that bound,
otherwise users can cause a panic via malloc getting hit with a
odd (huge or negative) amount of memory to allocate.

If you ever want to run midi(4) out of the giant lock, uncomment
MIDI_OUTOFGIANT in midi.h. Confirmed to work for csamidi with WITNESS
and INVARIANTS.
- midi_info, midi_open and seq_info are now tailqs, allowing arbitrary
numbers of devices to be configured.
- Do not send an active sensing message to reset midi modules.
- Clone /dev/sequencer*. /dev/sequencer0 and /dev/sequencer are generated
upon initialization.

- Convert to a more efficient queueing implementation.
- Don't allocate command buffers on the fly; simply work from a
static pool.
- Add a control device interface, for later use.
- Handle controller overload better as a consequence of the
improved queue implementation.
- Add support for the XPT_GET_TRAN_SETTINGS ccb, and correctly
set the virtual SCSI channels up for multiple outstanding I/Os.
- Update copyrights for 2001.
- Some whitespace fixes to improve readability.
Due to a misunderstanding on my part, previous versions of the
driver were limited to a single outstanding I/O per virtual drive.
Needless to say, this update improves performance substantially.
connection, but send it immediately. Prior to this change, it was possible
to delay a delayed-ack for multiple times, resulting in degraded TCP
behavior in certain corner cases.
o Offset and period in synch messages and width negotiation should be
done for per target not per lun. Move these from *lun_info to
*targ_info.
o Change in handling XPT_RESET_DEV and XPT_GET_TRAN_SETTINGS .
o Change CAM_* xpt_done return values.
o Busy loop did not timeout. Change this to timeout as original NetBSD/pc98.

Make double sure that genassym.o is built and nm'ed in elf mode.

requirement really, but to work around the bugs in the antique version of
gas that used for a.out. Makefile hacks are all that is needed to
get an a.out kernel. There is no telling if it will work though.
This is little more than an academic curiosity anyway since all it is
good for is situations where the boot code is hard wired, eg: rom
bootstraps (such as the gnat box).

Note that this does not affect the ability to generate an aout kernel

translated to 5.0 by me. man page not yet written.
This node still needs a little work.. don't use yet. Not yet linked into
the build.
This helps to stop it from geting out of sync.
It is not part of the normal build but I can use it with all the others
when I make changes to netgraph to ensure it is buildable.
