Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

o break newbus api: add a new argument of type driver_filter_t to
bus_setup_intr()

o add an int return code to all fast handlers

o retire INTR_FAST/IH_FAST

Make a pass and cleanup the printfs from this driver.

u_intXX_t -> uintXX_t while I'm here.

Remove duplicate $FreeBSD$

Noticed by: njl

Pass sc to GO_WINDOW macro.
Use SET_IRQ for pccard case, rather than exapnding it inline.

Requested by: mdodd

Whole grab-bag of changes:
o Make the driver MPSAFE
o Some changes due to diff reduction effort with vx.
o Removed some obsolete junk.

Reviewed by: sam, modd

Fix LINT build by correcting a missed change.

Use __FBSDID().
Also some minor style cleanups.

Style(9) cleanup. There was no consistent style in this driver, and
The next round of commits will be to fix up locking in it. This lot
is to at least give a consistent base to work off.

- Free interrupt handler in ep_free().
- Move ep_pccard_detach() to if_ep.c and rename to ep_detach()
- Specify detach methods for all bus frontends.

Remove 7 unnecessary includes frmo phk's script

HEADS UP! All 3c5x9 users!

- Rip out all the static softc stuff and do softc allocation the right way.
- Rewrite most of the ISA code so that it provides a DEVICE_IDENTIFY
method to enumerate all non-PnP ISA devices.

This has the following consequences:

- No 'ep' devices may be hardwired.
- All hardwired devices will probably be detected twice.
By hardwired I mean:

device ep0 at isa? port 0x300 irq 10

- 'ep' devices are ordered by bus, slot, and then MAC address.

- Make 3c509B cards work in PnP mode. Yes, they really work.
- Convert over to using ifmedia for media selection. No more of this
lame 'linkX' stuff.
- Consolidate a lot of duplicated code.
- Make a stab at not breaking MII based PCCARD devices.
I doubt that the PCCARD stuff works any more than it did before my
changes but theres hope. My PCCARD hardware should arrive in a
week or so.
- Retreive the media settings from the card EEPROM rather than guessing.
I've got a 3c509-TPO that thinks its got an AUI port and if others
can report similar problems I'll write a bit of clever code that will
fix this but right now it works correctly on all but 1 card.
- Clean up a few things and make some cosmetic changes.
- Add myself as the MAINTAINER since nobody else wants to. I'm
in the best position to do this as I've got an example of most
of the cards:

EISA 3c579 bnc/aui
MCA 3c529 tp/aui
ISA 3c509 tpo
ISA-PnP 3c509B combo

If someone wants to send me a any cards I don't have I'd appriciate
it. Also welcome are 3c59x boards since I'll be folding if_vx and
if_ep at some point.

- Split out the ISA and PCCARD specific code.

- Split out the prototypes, externs and struct decls from if_epreg.h into
if_epvar.h.

- Add support for MCA based Etherlink III (3c529) devices.

None of this code is used right now; the old if_ep driver is still
in place and used.

I will eventually get around to converting if_ep_isa.c to newbus once I've
had a talk with Peter and DFR about the DEVICE_IDENTIFY() method.

I have tested this code on my PS/2. It works. I would like EISA and ISA
testers since my example hardware hasn't arrived yet.

Add:

dev/ep/if_ep.c optional ep
dev/ep/if_ep_isa.c optional ep isa
dev/ep/if_ep_eisa.c optional ep eisa
dev/ep/if_ep_mca.c optional ep mca
dev/ep/if_ep_pccard.c optional ep card

to sys/conf/files

Remove:

i386/eisa/3c5x9.c optional ep
i386/isa/if_ep.c optional ep

from sys/i386/conf/files.i386

PCCARD testers wanted!

I will switch off and cvs rm the old driver in favor of this copy once
I've had positive feedback or have the hardware to verify that it works.
