perform the reboot action via the reset register instead of our legacy
method. Default is 0 (use legacy). This is needed because some systems
hang on reboot even though they claim to support the reset register.

- fix "No sound in KDE":
The problem is related to the implementation of Envy24(1712) hardware
mixer support in the driver. Envy24(1712) has very precise 36bit wide
hardware mixer, which is superior that vchans (software sound mixer in
the kernel). The driver supports Envy24(1712) hardware mixer, so up to
10 channels (5 stereo pairs) can be playback simultaneously.
However, there are problems with the implementation of Envy24(1712)
hardware mixer support in the driver, one of them is the problem with
"no sound in KDE":
When playing back several channels simultaneously and
stoping one of the channels, sound starts to stutter and
plays at very low speed.
Another problem is:
Playing back simultaneously more than one 24bit/32bit
sound file or 16bit sound file and 24bit/32bit sound
file doesn't work as expected.

shifting depends on the bus. The hardcoded shift was specific
to the SBus on sparc64. The shifted range is now determined at
run-time. This fixes the mac-io attachment.

desired role configuration instead of existing role. This gets
us out of the mess where we configured a role of NONE (or were
LAN only, for example), but didn't continue to attach the CAM
module (because we had neither initiator nor target role
set). Unfortunately, the code that rewrites NVRAM to match
actual to desired role only works if the CAM module attaches.

controller ported from NetBSD. It supports the following Gigabit
Ethernet adapters.
o Antares Microsystems Gigabit Ethernet
o ASUS NX1101 Gigabit Ethernet
o D-Link DL-4000 Gigabit Ethernet
o IC Plus IP1000A Gigabit Ethernet
o Sundance ST-2021 Gigabit Ethernet
o Sundance ST-2023 Gigabit Ethernet
o Sundance TC9021 Gigabit Ethernet
o Tamarack TC9021 Gigabit Ethernet
The IP1000A Gigabit Ethernet is also found on some motherboards
(LOM) from ABIT.
Unlike NetBSD stge(4) it does not require promiscuous mode operation
to revice packet and it supports all hardware features(TCP/UDP/IP
checksum offload, VLAN tag stripping/insertion features and JUMBO
frame) and polling(4).
Due to lack of hardware, hardwares that have TBI trantransceivers
were not tested at all.
Special thanks to wpaul who provided valauble datasheet for the
controller and helped to debug jumbo frame related issues. Whitout
his datasheet I would have spent many hours to debug this chip.

mac-io bus, we cannot setup FAST interrupt handlers. This because we
use spinlocks to protect the hardware and all interrupt resources are
assigned the same interrupt handler. When the interrupt handler is
invoked for interrupt X, it could be preempted for interrupt Y while
it was holding the lock (where X and Y are the interrupt resources
corresponding a single instance of this driver). This is a deadlock.
By only using a MPSAFE handler in that case we prevent preemption.
The register layout has changed since the original NV4 - sigh.
Hotplug support has been fixed for all nVidia chipsets that supports it
(including the MCP51/55).

- Move all the svr4 socket cache code into svr4_socket.c, specifically
move svr4_delete_socket() over from streams.c. Make the socket cache
entry structure and svr4_head private to svr4_socket.c as a result.
- Add a mutex to protect the svr4 socket cache.
- Change svr4_find_socket() to copy the sockaddr_un struct into a
caller-supplied sockaddr_un rather than giving the caller a pointer to
our internal one. This removes the one case where code outside of
svr4_socket.c could access data in the cache.
- Add an eventhandler for process_exit and process_exec to purge the cache
of any entries for the exiting or execing process.
- Add methods to init and destroy the socket cache and call them from the
svr4 ABI module's event handler.
- Conditionally grab Giant around socreate() in streamsopen().
- Use fdclose() instead of inlining it in streamsopen() when handling
socreate() failure.
- Only allocate a stream structure and attach it to a socket in
streamsopen(). Previously, if a svr4 program performed a stream
operation on an arbitrary socket not opened via the streams device,
we would attach streams state data to it and change f_ops of the
associated struct file while it was in use. The latter was especially
not safe, and if a program wants a stream object it should open it via
the streams device anyway.
- Don't bother locking so_emuldata in the streams code now that we only
touch it right after creating a socket (in streamsopen()) or when
tearing it down when the file is closed.
- Remove D_NEEDGIANT from the streams device as it is no longer needed.
renegotiation, we only initialize the hardware only when it is
absolutely required. Process SIOCGIFADDR ioctl in em(4) when we know
an IPv4 address is added. Handling SIOCGIFADDR in a driver is
layering violation but it seems that there is no easy way without
rewritting hardware initialization code to reduce settle time after
reset.
This should fix a long standing bug which didn't send ARP packet when
interface address is changed or an alias address is added. Another
effect of this fix is it doesn't need additional delays anymore when
adding an alias address to the interface.
While I'm here add a new if_flags into softc which remembers current
prgroammed interface flags and make use of it when we have to program
promiscuous mode.

instead of doing the first load with the BUS_DMA_NOWAIT flag. On 4.x with
PAE and > 4gb of RAM this proved disastrous if there weren't enough bounce
pages as amr_mapcmd() would return failure but the callback would later
fire once enough bounce pages were available and would then overwrite
another command's S/G list.

to always win on my amd64. This was not my intention, so have sio be
just a tiny bit more preferred than uart.
Note: I'm not making any judgement on the merits of uart winning. I'm
just saying that if we want to change it, we do it on purpose.
