It might not effect those cards.
I think the TG3 driver was changed to support the card im trying to use (Netgear GA302T) and similar.

curious.

i remember from the Tigon2 days, it didn't matter if you used a NetGear card, an Alteon card, or an Alteon card ripped out of the inside of an ACEDirector switch -- they were all the same reference design.

i don't believe that anyone using the bcm5700 would deviate significantly beyond the reference design - there wouldn't be any reason to.

(the only variants are probably due to dual-port versions ... of course, i'm sure the tg3 driver authors will now correct me on the differences. <grin>).


cheers,
