It's only enabled if the kernel enabled bridge AND tap.
Otherwise it's commented out.

Remove references to BRIDGE_IPF, it is now compiled in by default.

Add drvctl to kernel which has audio device.
audiocfg(1) requires drvctl(4).

Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

Remove "options IPKDB", and the other associated options, from the config
files.

ipkdb is being retired. Its code is really old, and hasn't kept pace with
today's expectations: IPv6, SMP, modern NICs. The associated code for x86
was already removed because it was too incorrect to stay.

There are plans to rewrite a similar feature from scratch.

swwdog(4): Add to GENERIC kernels.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:

Feel free to remove it from others that need to be kept smaller.

Compile-tested a few of these just in case:

Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

Eliminate all of the #ifdefs for the "strtc" driver. Define model

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Disable BSDLABEL and MBR DKWEDGE methods again since sysinst does not work
with wedges.

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options

New device nhpow(4) to support the onboard GPIO pins on a NH230/231 board for
buttons, powerdown, reset, LEDs and fan control. It attaches gpio(4) for
its 8 pins on demand.

Disable flash device unless nor(4) is not finished.
Add pcf8563rtc(4) for NH230/231.

Add a workaround for the VT6410 IDE controller on the Iomega Storcenter.
Its interrupt cannot be disabled and remains asserted during the whole
device probing procedure, causing an interrupt storm.
This was fixed by establishing an edge-triggered interrupt for it, so it
will trigger only once during probing.
This workaround makes the WDC_NO_IDS option obsolete, which was removed
from the GENERIC config.

WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

Added NOR flash driver, using nor(4) and flash(4).

GENERIC.NAS and RAMDISK are no longer needed.

At least KuroBox Classic and HG seem to have buggy UART, for which
ETXRDY interrupts are sometimes (once per a few hours?) lost; TX stalls
until next RX arrives.

Since interrupt-based I/O works just fine for other devices, I believe
this problem is due to UART and not to PIC or its driver.

In order to work around this bug, enable COM_HW_BROKEN_ETXRDY bit, as
well as carry out polling once per 10 sec or 1k tics (arbitrary, but
1 min seems too long).

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)

that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other

- Added the new naming convention.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
