Networking :: DSL Doesnt see NW Device

I loaded DSL from CD on a Radisys Endura SBC but cannot get the network to come up.

The N/W interface is a Broadcom Netlink BCM5789 and lspci does show it as an Ethernet interface; however, it also says it is an unknown device.

The driver (tg3) exists but it fails when invoked by modprobe because it cannot find the device.

Any suggestions are appreciated.
