A little off-topic, but how do you know if it is dual-core or not?

What driver does it use?

On my system, `dmesg | grep eth0' gives this output

eth0: Tigon3 [partno(BCM95703A30) rev 1002 PHY(5703)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:e0:81:2c:8b:d1

So I deduced that the driver is tg3.

The card is different (Broadcom Corporation NetXtreme BCM5703X Gigabit
Ethernet (rev 02)), but maybe you use the same driver?

Curiously,
