canonical: define a versioned struct xswdev, and add a sysctl node
handler that allows the user to get this structure for a certain device
index by specifying this index as last element of the MIB.
This new node handler, vm.swap_info, replaces the old vm.nswapdev
and vm.swapdevX.* (where X was the index) sysctls.
memory I/O space. Otherwise, our resource allocation system might
mistakenly assign pccard, plug and play devices or other things
addresses that conflict with ROMs.
I cleaned up his code a little from the submited driver: style(9)
issues, commentary on why something that looks incorrect really is
correct. Also noted that while a checksum field is defined for the
ROMs, enough common hardware neglects it to make it not worthwhile
checking.

the interface conversion to platform.pci_intr_route(). I've left the
platform.pci_intr_route() function pointer in place, as well as
alpha_pci_route_interrupt(), but no platform currently implements it.
To work around the removal of alpha_platform_assign_pciintr(cfg);
from the pci probe code, I've hooked in calls to platform.pci_intr_map()
in pcib_read_config (similar to the x86 APIC_IO ifdef in pci_cfgregread)
for every chipset that has a platform which needs it.
While here, I've removed the interupt mapping/routing code from the
AS2x00 platform because its not required (it has never been present in
-stable).

Only tun0 -> tun32767 may now be opened as struct ifnet's if_unit
is a short.
It's now possible to open /dev/tun and get a handle back for an available
tun device (use devname to find out what you got).
The implementation uses rman by popular demand (and against my judgement)
to track opened devices and uses the new dev_depends() to ensure that
all make_dev()d devices go away before the module is unloaded.

apparently broke the clnt_control CLGET_SVC_ADDR options.

- move the sysctl code to kern_intr.c
- do not use INTRCNT_COUNT, but rather eintrcnt - intrcnt to determine
the length of the intrcnt array
- move the declarations of intrnames, eintrnames, intrcnt and eintrcnt
from machine-dependent include files to sys/interrupt.h
- remove the hw.nintr sysctl, it is not needed.
- fix various style bugs

This closes a minor information leak which allows a remote observer to
determine the rate at which the machine is generating packets, since the
default behaviour is to increment a counter for each packet sent.

setting the 'max packet size' register in window 3. This only
works for cards based on the cyclone or newer chipsets (i.e. it
won't work with the original 3c905/boomerang cards).
There is a trick which will work with the boomerang, which is to turn
on the 'large packets ok' bit in the MAC control register, however this
lets the chip accept any frame up to 4K in length, which is larger than
the mbuf cluster buffers we use to receive frames. If somebody sends us
such a frame and the chip DMAs it to us, it could write past the end
of the cluster buffer and clobber something.
