It seems RTL8169/RTL8168/RTL810xE has a kind of interrupt
moderation mechanism but it is not documented at all. The magic
value dramatically reduced number of interrupts without noticeable
performance drops so apply it to all RTL8169/RTL8169 controllers.
Vendor's FreeBSD driver also applies it to RTL810xE controllers but
their Linux driver explicitly cleared the register, so do not
enable interrupt moderation for RTL810xE controllers.
While I'm here sort 8169 specific registers.

o) Fix enumeration of PHY addresses on the MR-955.
o) Parse link state for the MR-730 using the Broadcom PHY support in the SDK.
It's not clear that this is entirely-correct, but it seems to work. Since
this board uses a BCM5482S, this may mean that we work correctly for copper
but not SFI, which is untested.
- Register APIC enumerators at SI_SUB_TUNABLES - 1 instead of SI_SUB_CPU - 1.
- Probe CPUs at SI_SUB_TUNABLES - 1. This allows i386 to set a truly
accurate mp_maxid value rather than always setting it to MAXCPU - 1.

acpi.ko could always include the MADT parsing code and still link with a
kernel that did not include 'device apic'.

register local APIC errors during boot on a CPU that doesn't support those

There were a couple of attempts in the past to reduce it since it
took more than 1ms. Because mii_tick() periodically polls link
status, waiting more than 1ms for each GMII register access was
overkill. Unfortunately all previous attempts were failed with
various ways on different controllers.
This time, add additional 20us dealy at the end of GMII register
access which seems to requirement of all RealTek controllers to
issue next GMII register access request. This is the same way what
Linux does.
numbers. bge(4) supports too many models such that it's
unreasonable to list all these controllers in one line description
of name. While I'm here mention that BCM590x/BCM5779x is Fast
Ethernet controller.
bge(4) still lacks support for some controllers but supporting
these controllers should be easy now and adding new controllers
do not require touching .Nd any more.

- Use KERNCONFDIR with KERNCONF instead of copying the kernel config into the source tree
so included kernel configs work.
- Put more stuff in the _.bk/_.ik log file, not just make statements.
- Add the kernel config name to the pprint during kernel installation.
- Add NANO_MODULES providing a list of modules to build and install.

ensure that grow_amount is a multiple of the page size. Otherwise, the
kernel may crash in swap_reserve_by_uid() on HEAD and FreeBSD 8.x, and
produce a core file with a missing stack on FreeBSD 7.x.

actually 16 I/O lines but the other ones are used for system devices and
interrupts.
The IXP4XX platform can set interrupts on these pins for
high/low/rising/falling/transitional but this is not implemented yet.
The Cambria has the same interface but as all the pins are assigned to system
functions the gpio header is toggled via a PLD on the i2c bus and is not
supported by this commit.
