[9fans] Intel PRO/100 VE (82562)

[Adrian Tritschler]

I see that there's a driver for the 82543 gigabit ethernet, is it likely 
to be a minor change to include the 82562 cards, or would it need a 
whole new driver?  I seem doomed to spend my life finding machines that 
I can put plan9 on that have all but one bit of hardware supported!

My latest acquisition is a P4 with the above Intel network card, a 
Matrox G450 that seems to only work at 640x480x8 and ATA and SATA disk 
controllers where only the parallel ATA is recognised!  Oh yeah, and its 
got a funny two-button mouse with a wheel on top too...

The relevant line from pci.txt is:
2.8.0:  02.00.00 8086/1050   9 0:feaff000 4096 1:0000bc01 64

You can always replace the existing ethernet card (or augment it, if
it's actually a built-in chip set or ASIC or something).  The `Intel
PRO/1000 MT Desktop Adapter', which is supported, are down to US$53.48
on buy.com, for example.  I bought a pair of these a while ago, for my
file server and main cpu server (when gigabit switches were a lot more
expensive), and adapted the driver to the file server kernel, but then
realised that I should first replace my IDE cache disk with a SCSI
because the fs kernel's IDE driver doesn't use DMA, and it's
noticeably slower than using a SCSI disk (in part because my big RAM
cache tends to get flushed each night; it's a long story).  And none
of this has got done while I'm looking for full-time employment.

Try adding the device ID 0x1050 to the relevant case in ether82557.c
and let me know what happens, e.g.

		switch(p->did){
		default:
			continue;
		case 0x1031:		/* Intel 82562EM */
		case 0x1050:		/* */
		case 0x2449:		/* Intel 82562ET */
			nop = 1;
			/*FALLTHROUGH*/
		case 0x1209:		/* Intel 82559ER */
		case 0x1229:		/* Intel 8255[789] */
			break;
		}

There may be bugs/features to be worked around, but I think it's just
another variant of the 82557 embedded in a hub.
