there's a bug in vmware's virtual ether card.  did you catch this
in the current driver's reset function?

	while(!(ctlr->ior(ctlr, Rdp) & Idon))
		;

	/*
	 * We used to set CSR0 to Idon|Stop here, and then
	 * in attach change it to Iena|Strt.  Apparently the simulated
	 * 79C970 in VMware never enables after a write of Idon|Stop,
	 * so we enable the device here now.
	 */
	ctlr->iow(ctlr, Rdp, Iena|Strt);
	ctlr->init = 0;
	iunlock(ctlr);

	/*
	 * Linkage to the generic ethernet driver.
	 */

I see you're back.  If it's OK with you, I'd like some help with
the PCnet driver.  I have it working OK for the 79c960 even under
4ed, but under VMware it is more than a little shaky.

I'll be back in my office from Thursday, then I'll be able to
refresh my memory.  I recall thinking that the symptoms would strike
you as much more meaningful than to me.  I think it had to do with
not getting the interrupt from VMware, but I'll be a lot clearer
once I've taken a good look.

PS:  I have reworked the whole thing into (a) a single source file
(heretical as it may be) and (b) with the indirect function calls you
added for 16- and 32-bit operation.

PPS:  Of course, if you aren't going to be able to help, I'll bounce
it all off the mailing list, but I thought the whole issue could wait
until you had a chance to let me know.

... and other embarrassing details :-(

Sorry, all.  Mutt asked me if it should include the mailing list, and
I explicitly answered "no".  I didn't think of actually checking.
