Ethernet Controllers

Internal Ethernet controller

A variety of Ethernet controllers is integrated into almost all models starting with the introduction of the A, T and X series.

The Ethernet controller is located on either a MiniPCI card, Communications Daughter Card (CDC), or integrated on the systemboard.

Broadcom Fast Ethernet (10/100)

Driver: tg3 or bcm5700

This chip is integrated into select systemboards of the following machines:
Broadcom BCM5901

• G40, G41
• R40e

Broadcom BCM5751F

• R51e

Broadcom Gigabit (10/100/1000)

Driver: tg3 or bcm5700

This chip is integrated into select systemboards of the following machines:

Broadcom BCM5752M

• Z61e

Broadcom BCM5751M

• R52, R60
• G41
• T43, T43p
• X41, X41 Tablet
• Z60m, Z60t
• Z61m, Z61p

Note: There are some problems with the driver since kernel 2.6.17 (at least on a Z61p, Z61m). After an ifdown && ifup it doesn't work anymore. A possible workaround is to build the tg3-driver as a module and reload it when this problem occours. (Adding pre-up modprobe tg3 and post-down rmmod tg3 to the corresponding section in /etc/network/interfaces works fine.) Rebooting the machine would also be possible. This is fixed in kernel 2.6.19-rc5.

The T43 with a stock Linux 2.6.18.1 kernel does not have any problems.
