that's good to hear!

but of course my poor little 21041 card is only 10baseT

	de0 at pci0 dev 11 function 0
	de0: interrupting at irq 10
	de0: SMC 21041 [10Mb/s] pass 1.1
	de0: address 00:00:c0:83:c3:e9

(the chip actually has a "digital" label on it, not SMC....  but the
card's definitely of SMC origin)

It's significantly faster, both at small packets (ping -f) and bulk TCP
transfers, than any of the 10/100 "rtk" based cards I've got (on the
same 10baseT network).

In fact I've been thinking of replacing two rtk cards in my gateway
router with another pair of these 21041 cards -- the rtk cards seem to
be causing strange problems when faced with even minimal collision rates.
