ID, plus the ability to force '16-bit mode' which really means NE-2000
mode. Other open source drivers suggest that the Holtek misbehaves if
you allow the 8-bit probe. Also, all of the PCI chips emulate
NE-2000ish cards, so always force 16-bit mode for memory transfers.
PR: 84202 (patch not used)
succeeded and a subsequent interation failed to find an
entry to prune, it could loop infinitely, since the
"freed" variable wasn't reset to FALSE. This patch moves
setting freed FALSE to inside the loop to fix the problem.

I'm not sure whether adding this logical id is correct or not
because Compex RL2000 is in the list of supported hardware list.
I guess the Compex RL2000 could be PCI variant while the controller
in question is ISA controller. It seems PNP compat id didn't match
or it had multiple compat ids so isa_pnp_probe() seemed to return
ENOENT.
PR: kern/80853
resetting needfree
needfree is checked at the very start of arc_reclaim_needed.
This change makes code easier to follow and maintain in face of
potential changed in arc_reclaim_needed.
Also, put the whole sub-block under _KERNEL because needfree can be set
only in kernel code.
To do: rename needfree to something else to aovid confusion with
OpenSolaris global variable of the same name which is used in the same
code, but has different meaning (page deficit).
Note: I have an impression that locking around accesses to this variable
as well as mutual notifications between arc_reclaim_thread and
arc_lowmem are not proper.

This will allow conforming applications to differentiate between
signals generated by standard events and those generated by other

support WOL. Some controllers require additional 3-wire auxiliary
remote wakeup connector to draw power. More recent xl(4)
controllers may not need the wakeup connector though.
initialize controller from a known good state. Previously driver
used to issue controller reset while TX/RX DMA are in progress.
I guess resetting controller in active TX/RX DMA cycle is to ensure
stopping I/Os in xl_shutdown(). I remember some buggy controllers
didn't respond with stop command if controller is under high
network load at the time of shutdown so resetting controller was
the only safe way to stop the I/Os. However, from my experiments,
controller always responded with stop command under high network
load so I think it's okay to remove the xl_reset() in
device_shutdown handler.
Resetting controller also will clear configured RX filter which
in turn will make WOL support hard because driver have to reprogram
RX filter in WOL handler as well as setting station address.
Use MACHINE_CPUARCH in preference to MACHINE_ARCH. The former is the
source code location of the machine, the latter the binary output. In
general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless
we're tesitng for a specific target. The isn't even moot for
i386/amd64 where there's momemntum towards a MACHINE_CPUARCH == x86,
although a specific cleanup for that likely would be needed...

register mapping. I'm not sure whether it comes from the fact that
controllers live behind certain PCI brdge(PLX PCI 6152 33BC) and
the bridge has some issues in handling I/O space register mapping.
Unfortunately it's not possible to narrow down to an exact
controller that shows this issue because RealTek used the same PCI
device/revision id again. In theory, it's possible to check parent
PCI bridge device and change rl(4) to use memory space register
mapping if the parent PCI bridge is PLX PCI 6152. But I didn't try
to do that and we wouldn't get much benefit with added complexity.
Blindly switching to use memory space register mapping for rl(4)
may make most old controllers not to work. At least, I don't want
to take potential risk from such change. So use I/O space register
mapping by default but give users chance to override it via a
tunable. The tunable to use memory space register mapping would be
given by adding the following line to /boot/loader.conf file.
dev.rl.%d.prefer_iomap="0"
This change makes P811B quad-port work with this tunable.
