23e4757cd7 This commit adds device driver support for the Sundance Technologies ST201
PCI fast ethernet controller. Currently, the only card I know that uses
this chip is the D-Link DFE-550TX. (Don't ask me where to buy these: the
only cards I have are samples sent to me by D-Link.)

This driver is the first to make use of the miibus code once I'm sure
it all works together nicely, I'll start converting the other drivers.

The Sundance chip is a clone of the 3Com 3c90x Etherlink XL design
only with its own register layout. Support is provided for ifmedia,
hardware multicast filtering, bridging and promiscuous mode.

fa62586ae7 This is the addition of a syslog(3) security.* top-level category. This
should be used from now on for anything security but not auth-related.
Included are updates for all relevant manpages and also to /etc files,
creating a new /var/log/security. Nothing in the system logs to
/var/log/security yet as of the time of this commit.

d00275330d This commit adds support for the NetBSD MII abstraction layer and
MII-compliant PHY drivers. Many 10/100 ethernet NICs available today
either use an MII transceiver or have built-in transceivers that can
be programmed using an MII interface. It makes sense then to separate
this support out into common code instead of duplicating it in all
of the NIC drivers. The mii code also handles all of the media
detection, selection and reporting via the ifmedia interface.

This is basically the same code from NetBSD's /sys/dev/mii, except
it's been adapted to FreeBSD's bus architecture. The advantage to this
is that it automatically allows everything to be turned into a
loadable module. There are some common functions for use in drivers
once an miibus has been attached (mii_mediachg(), mii_pollstat(),
mii_tick()) as well as individual PHY drivers. There is also a
generic driver for all PHYs that aren't handled by a specific driver.
It's possible to do this because all 10/100 PHYs implement the same
general register set in addition to their vendor-specific register
sets, so for the most part you can use one driver for pretty much
any PHY. There are a couple of oddball exceptions though, hence
the need to have specific drivers.

There are two layers: the generic "miibus" layer and the PHY driver
layer. The drivers are child devices of "miibus" and the "miibus" is
a child of a given NIC driver. The "miibus" code and the PHY drivers
can actually be compiled and kldoaded as completely separate modules
or compiled together into one module. For the moment I'm using the
latter approach since the code is relatively small.

Currently there are only three PHY drivers here: the generic driver,
the built-in 3Com XL driver and the NS DP83840 driver. I'll be adding
others later as I convert various NIC drivers to use this code.

I realize that I'm cvs adding this stuff instead of importing it
onto a separate vendor branch, but in my opinion the import approach
doesn't really offer any significant advantage: I'm going to be
maintaining this stuff and writing my own PHY drivers one way or
the other.

f996ef6395 Loosen up the constructed argument segment generation slightly; rather than
trying to size it intelligently just make it 64k and leave it up to the caller
to ensure that the arguments all fit within that range.

This should resolve the issue that some people were seeing with the PnP BIOS
scan crashing on a large PnP node.

9212e4c73a There may exist two kinds of IBM BlueLightning CPU. One is that 5/2
test does not change undefined flag like Cyrix CPUs.  Another is that
5/2 test changes undefined flag like Intel CPUs.  Latter one could not
be detected and was recognized 486DX CPU.  To solve this,
finishidentcpu() calls identblue() when cpu_vendor is null string
(that is, CPUID instruction is not supported) and cpu == CPU_486.
Tests have been done on IBM BlueLightning CPUs, i486SX and i486DX.

3ece1bd296 Fix short timeout problems with the pt(4) driver:
- increase the default timeout from 10 seconds to 60 seconds
- add a new kernel option, SCSI_PT_DEFAULT_TIMEOUT, that lets users specify
  the default timeout for the pt driver to use
- add two new ioctls, one to get the timeout for a given pt device, the
  other to set the timeout for a given pt device.  The idea is that
  userland applications using the device can set the timeout to suit their
  purposes.  The ioctls are defined in a new header file, sys/ptio.h

e9fc0b372f Replace the tulip_delay_300ns() with a DELAY(1). Hammering the PCI bus
to achieve a delay is pretty mean.

Andrew reports:
"The tulip_delay_300ns() is, well, bloody stupid on machines with a
heavily loaded PCI bus.  It tries to do a delay by assuming PCI reads
will take a certain amount of time & issues a large amount of
(expensive, 5% CPU when your PCI bus is heavily loaded) pci reads.

Locally, we've replaced the calls to tulip_delay_300ns(sc) in the EMIT
macros with a simple DELAY(1) and not seen any problems.  Plus we've
gained about 50Mb/sec throughput on our gigabit network cards because
of the added PCI bus bandwidth available."

Also, I do not understand why, but this change appears to stop the
Transmit Fifo underrun on one of my systems (but not the Alpha PC164SX).
This shouldn't make that much of a difference since the mii bus isn't
touched all that often, but perhaps when it does get accessed and hence
hammers the register, it was causing the chip to get upset.

264c3d8738 Undo my previous commit and do it differently. Break the ffs() etc macros
into two parts - one to do the bsfl and the other to convert the result
(base 0) to ffs()-like (base 1) in inline C.  This enables the optimizer
to be a lot smarter in certain cases, like where it knows that the argument
is non-zero and we want ffs(known non zero arg) - 1.  This appears to
produce identical code to the old inline when the argument is unknown.
