This is an architecture that present a thing message passing interface
to the OS. You can query as to how many ports and what kind are attached
and enable them and so on.
A less grand view is that this is just another way to package SCSI (SPI or
FC) and FC-IP into a one-driver interface set.
This driver support the following hardware:
LSI FC909: Single channel, 1Gbps, Fibre Channel (FC-SCSI only)
LSI FC929: Dual Channel, 1-2Gbps, Fibre Channel (FC-SCSI only)
LSI 53c1020: Single Channel, Ultra4 (320M) (Untested)
LSI 53c1030: Dual Channel, Ultra4 (320M)
Currently it's in fair shape, but expect a lot of changes over the
next few weeks as it stabilizes.

The driver is mostly from some folks from Jeff Roberson's company- I've
been slowly migrating it to broader support that I it came to me as.
The hardware used in developing support came from:
FC909: LSI-Logic, Advansys (now Connetix)
FC929: LSI-Logic
53c1030: Antares Microsystems (they make a very fine board!)

code to do it when the bios doesn't do it for us, flag it. Then, when
we dealloc, do an equal kludge to get rid of the address. This should
address the can't get IRQ and panic bug in a more graceful way.
# really should write a dealloc routine and just call it instead, since
# this might not fix things in the kldunload case.
The CAM<>ATAPI layer was submitted by "Thomas Quinot <thomas@cuivre.fr.eu.org>"
changes form the version on the net by me (formatting, ability to be used
alone without the ATAPI native device driver, proper speed reporting...)
See /sys/conf/NOTES for usage.

Enjoy!
- bus_space'ify
- generate fake ethernet address using read_random() instead of reading
from timer i/o ports
Other minor fixes:
- remove "hack" in connect_to_master()
- use M_ZERO
- remove unused variable in sbni_ioctl()
- properly release irq in sbni_attach_isa() on attach errors
and the AT24C08 small serial flash parts. We still report these as
the same part (since we group things already), but now we recognize
the small serial versions as well.
firmware revision as well (not sure which firmware versions are needed
for this, but the 6.x and 8.x 'software' versions that I have seem to
support it).
Add dBm comm quality RID. This is like the normal comm quality rid,
except the signal and noise numbers are normalized to dBm. Some
revisions of the prism firmware, however, don't support this RID, and
some that do support it return 0 for quality and/or noise. Your
milage may vary.
Also take this chance to cleanup the code in fxp_intr_body.
Add a missing block of code to disable interrupts when
reinitializing the interface while doing polling (the RELENG_4
version was correct).

cards. Since the firmware is hard coded into the kernel, I've made it
a kernel option (WI_SYMBOL_FIRMWARE).
Note: This only downloads into the RAM of these cards. It doesn't
download into FLASH, and is somewhat limited. There needs to be a
better way to deal, but this works for now. My Symbol LA4132 CF card
works now.

sizes. Previously, the end result was at the mercy of the card's default
setting. This change will reduce the number of buffer underruns for
some users.

RAID's has to be setup via the BIOS on the SuperTrak, but all RAID
types are supported by the driver. The SuperTrak rebuilds failed arrays
on the fly and supports spare disks etc etc...
Add "device pst" to your config file to use.
As usual bugsreports, suggestions etc are welcome...

tweaked by sysctl we don't need to go through hoops to get the
different usb parts to produce debug data.
