ifconfig and bogus ethernet address (4b:57:4b:57:4b:57) has been
hacked around.  I'll revisit this when I have a clue whats going on.

Fix the performance problems I caused by setting ifq_maxlen to 8.

2000-01-12T05:27:08+00:00

Use IFQ_MAXLEN instead.  This seemed like a good idea at the time since
most 3c509s have all of 2k for their TX fifo.  My intention was to revisit
ifq_maxlen and auto-scale it or something.

I've got some tweaks that move the TX speed up to the RX speed but I've
got to groom them from the mess I've made of my source tree.

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.

Add newbus attachment for pccard driver. Heavily tested by me, and

1999-10-25T02:52:16+00:00

I'm committing this from a laptop running this driver.  Have only one
devclass for all ep devices (at least for pccard and eisa) so unit
numbering is sane.  Might not work with both isa and non-isa devices
on the same system until ep is updated (Matt has some patches in the
pipeline which should resolve this, he wanted me to commit this so he
can resolve any conflicts against cvs rather than my patches).

- Split out the ISA and PCCARD specific code.

1999-09-26T06:42:36+00:00

- 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.

Remove NBPF conditionality of bpf calls in most of our network drivers.

1999-09-25T12:06:01+00:00

This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.
