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.
- new EV_SET macro,
- NOTE_LOWAT option for low water marks on read/write filters,
- NOTE_REVOKE for filesystem unmounting (and revoke() calls)
- improved API for EVFILT_AIO

- 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.
libssl, for example), and hide it behind a make.conf option,
WANT_OPENSSL_MANPAGES, instead of having it commented out. We still can't
install these by default because of clobbering of a number of system
manpages with the same name, but they're there for people who want them.
