I have a Dell 2550 with a Dell Broadcom Nic/BMC5700.

I need to set the NIC to 100 FULL, Auto negotiate.

Using the Ethtool, I am able to temporary set the Nic to 100/full, etc....
ethtool eth0 speed 100 duplex full autoneg off (seems pretty simple)

The issue, when I try to copy files, it seems to hang server.

When I reboot server the 100 Full settings do not stick.

I've been able to set the NIC on a newer Dell server to my satisfactiion, however I can not set it on this server.

Anyone have any ideas on what i can try next?
