Gigabit eth card (was Re: Click Information

[Marcelo Pias]

Hi Eddie,

     I'm planning my experiments... So, I'm looking at gigabit for eth
cards to buy. Do you know if any gigabit device driver for linux/freebsd
was modified to include polling? If not, how difficult would be to
modify a DD for a gigabit card? When looking at performance, it
seems that the 3Com 3C996 is the card to buy. Would you recommend
another card?

     Thanks. Marcelo
