adapters. This is necessary in order to make this driver work with
the built-in ethernet on the alpha Miata machines. These systems
have a 21143-PC chip on-board and optional daughtercards with either
a 10/100 MII transceiver or a 10baseT/10base2 transceiver. In both
cases, you need to twiddle the GPIO bits on the controller in order
to turn the transceivers on, and you have to read the media info
from the SROM in order to find out what bits to twiddle.
Add lockdestroy() and appropriate invocations, which corresponds to
lockinit() and must be called to clean up after a lockmgr lock is no
longer needed.
this just involves adding the chip ID to the supported list: the PCnet/PRO
is compatible with the PCnet/FAST+ and friends and should "just work"
with this driver.

i386/isa/pcibus.c. This gets -current running again on multiple host->pci
machines after the most recent nexus commits. I had discussed this with
Mike Smith, but ended up doing it slightly differently to what we
discussed as it turned out cleaner this way. Mike was suggesting creating
a new resource (SYS_RES_PCIBUS) or something and using *_[gs]et_resource(),
but IMHO that wasn't ideal as SYS_RES_* is meant to be a global platform
property, not a quirk of a given implementation. This does use the ivar
methods but does so properly. It also now prints the physical pci bus that
a host->pci bridge (pcib) corresponds to.

constant. The hardcoded way was too specific to the particular card
I had and caused PHY probing to fail on at least one laptop with a
built-in AMD chip.

Previously, these cards were supported by the lnc driver (and they
still are, but the pcn driver will claim them first), which is fine
except the lnc driver runs them in 16-bit LANCE compatibility mode.
The pcn driver runs these chips in 32-bit mode and uses the RX alignment
feature to achieve zero-copy receive. (Which puts it in the same
class as the xl, fxp and tl chipsets.) This driver is also MI, so it
will work on the x86 and alpha platforms. (The lnc driver is still
needed to support non-PCI cards. At some point, I'll need to newbusify
it so that it too will me MI.)
The Am79c978 HomePNA adapter is also supported.

Maintaining compatability with NetBSD makes what should be very simple

- Move the 'struct intrec' type which describes interrupt sources into
sys/interrupt.h instead of making it just be a x86 structure.
- Don't create 'ithd' and 'intrec' typedefs, instead, just use 'struct ithd'
and 'struct intrec'
- Move the code to translate new-bus interrupt flags into an interrupt thread
priority out of the x86 nexus code and into a MI ithread_priority()
function in sys/kern/kern_intr.c.

a link. We check the subsystem ID and don't flip the LED control

bus/slot/function numbers. The old PCI code used other markers or
something, but without it here under the new pci code it is very hard to
tell which device is which (this only affects bootverbose mode).
In the nexus case, there are no ivars for children of nexus devices,
and we were passing data in from before the device existed, hence ivars
are convenient as the softc doesn't really exist yet.
However, for pci->pci bridges, the pcib occupies a pci device itself,
which *does* already have ivars. However, softc is available and stable
at this point since we've been identified and are locating the bus during
attach. So, use softc for this version of pcib devices for storing the
physical bus number in.
