bcm5700 problem

I have a problem about the bcm5700 driver for setting speed to Gigabit.

I try input options to modules.conf as below.
alias eth0 bcm5700
alias eth1 bcm5700
options bcm5700 auto_speed=0,0 line_speed=1000,1000 full_duplex=1,1

everyone, I just active eth1 on boot up, it work. but I try to active eth1. The results is...
eth0 is down and linespeed auto switch to 100mb
eth1 is active and linespeed is 1G

Hi Ryan,

As far as I know (but I'm not sure), speed cannot be forced to 1000 at the server. Gigabit speed must be auto-negotiated. You should leave the default options and check your gigabit switch.

Good luck.

Re: bcm5700 problem

Kodjo is correct.

You can't force Gibabit speeds, it must be autonegotiate. To get that off that NIC, you need the right driver.

The only gigabit card or nic I have every gotten to work right with Linux is Intel.

Re: bcm5700 problem

bcm5700 works well, however you must use the one provided by HP. You can also try tg3 that is already included in the Linux distro.

Good luck.

Re: bcm5700 problem

the switch force to 1000mb /full duplex. Can i set options into modules.conf as below

options bcm5700 auto_speed=1,1 line_speed=1000,1000 full_duplex=1,1

Re: bcm5700 problem

After booting try using ethtool. Once things work, may be then you can update modules.conf
