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

This driver actually works slightly better on -stable than on -current
(the system locks on detach on -current), so it should be MFC'd somewhat
sooner.
This driver currently points out a difficulty in the sound device framework.
The PCM unregister routine is allowed to refuse the detach if the device is
in use. In the case of a USB device, however, this unregistration is much more
mandatory in nature, since the device is *actually* gone when this call is
made. The sound subsystem really should not refuse an unregistration and
should take its own steps to reject further I/O. As a result, if you detach
a USB sound device while it is in use, you can expect a panic shortly
thereafter.
This device cannot currently record audio. Some routines are unwritten as
of yet in uaudio.c to support recording.

turns out that there's something of a hole in our new fabric name
server stuff. We ask the name server for entities that have
registered as a specific type. That type is FC-SCSI. If the entity
hasn't performed a REGISTER FC4 TYPES, the fabric nameserver won't
return it.
This brings this driver to a bit of a fork in the road as to what
the right thing to do is. For servicing the needs of accessing
FC-SCSI devices, this method is fine, and to be preferred. It is
extremely unlikely we're interested in fabric devices that *don't*
register correctly. If I ever get around to adding an FC-IP stack,
then asking for devices that have registers as FC-IP types is also
the right thing to do.
So- asking the fabric nameserver for a specific type is fine, *as
long as you are only interested in specific types*. If, on the other
hand, you want to create (as for management tool support) a picture
of everything on the fabric, this is *not* so fine. There are a
large class of FC-SCSI *initiators* who *don't* correctly register,
so we never will *see* them.
Is this a problem? Yes, but only a little one. If we want to do such
management tool support, we should probably run a *different* fabric
nameserver query algorithm. Better yet, we should talk to the management
nameserver in Brocade switches instead of the standard FC-GS-2 fabric
nameserver (which can be unwieldy).
Other changes: if we've overrrides marked, don't set some default
values from reading NVRAM. This allows us to override things like
EXEC throttle without having to ignore NVRAM entirely.

up when operating in PCI-X mode. For some received packets there is
data corruption in the first few bytes in that case. Aligning the
packet buffer eliminates the corruption. With this fix, the code
that offsets the packet buffer up by 2 bytes to align the payload is
disabled for BCM5701s operating in PCI-X mode. On the i386, which
permits unaligned accesses, the payload is left unaligned. On other
platforms, the packet is copied after reception to force alignment
of the payload. Obviously, this work-around reduces performance in

for supported 32-bit arches. Hundreds if not thousands thousands of
previously "fixed" daddr_t printings are now broken on 32-bit machines
by casting daddr_t's to longs. daddr_t's should be printed using %jd
format, but this fix uses %lld since %j is not implemented in the
kernel yet.
Fixed some nearby format printf errors (style bugs).
make_dev() to create device nodes for each of the serial port channels

the rc driver to work in 5.0. I've tested it with only one card, but
will try sticking in a second card tomorrow and see what happens.
the former blocks software interrupts, while the latter blocks
hardware interrupts.
Avoid one place where I'm at splnet across a call to copyout. Leave

I'll fix it in a subsequent commit.

allow recovery from transmission lockups which occur in the middle
of the descriptor list, rather than just at the beginning.
For some unknown reason, Rhine II chips have a tendency to stop
transmitting while under heavy load, possibly due to collisions.
Whether this behavior is due to a hardware bug or a driver glitch
is unknown as of now.
In either case, this change allows the driver to gracefully recover
from such situations.

bugged me into looking at this and to
Dominic Marks <dominic_marks@btinternet.com>, who performed a great
deal of testing to help characterize this problem.

previously used "micro-optimization" (count-down loop) into a
pessimization. Now the loops are written in the more natural count-up
form.
Also, while being there, i made the logic in out_fdc() similar to the
logic in in_fdc(). The old implementation was a bit bogus anyway
since it first tested the DIO bit and only afterwards the RQM bit.
However, according to the description of the i82077, the DIO bit is
only guaranteed to be valid once the RQM bit is set. Thus, the old
implementatoin would have had the chance to misbehave on a controller
that is implemented in accordance with the i82077 description (but is
not bug-for-bug compatible).

This bug was only detected because my version of <stddef.h> has some
spelling fixes (s/field/member/g) and gcc is now sensitive to the spelling

what could be achieved with a loop around DELAY(1), increase loop

Also, move the declaration of FDSTS_TIMEOUT out from fdreg.h into fd.c

This is said to fix the problem on some Compaq hardware (and perhaps

driver failed to operate at all.

Switch to USB_USE_SOFTINTR. The callout hack does indeed work
fine for systems without generic soft interrupts, even if it is
a little sub-optimal. Consider it a penalty for ports not
implementing a kernel API.
Addresses kern/11957. The PR has been open for 4 months, and
I have work blocked on the continued existence of splimp() in
the networking code.
The NetBSD patch only switches it on for NetBSD, but I've also
switched it on for FreeBSD in this commit.

Ensure that no one can fsetown() to a dying process/pgrp. We need
to check the process for P_WEXIT to see if it's exiting. Process
groups are already safe because there is no such thing as a pgrp
zombie, therefore the proctree lock completely protects the pgrp
from having sigio structures associated with it after it runs
funsetownlst.
Add sigio lock to witness list under proctree and allproc, but over
proc and pgrp.

This is temporary hack, better and generalized solution probably

Our current MII/PHY state-engine is not able to deal with PHY

to use the link/status change call-back mechanism. It seems that
MII/PHY was orphaned before it grew up.
