We have a board where the ethernet is on a plugin module and may or may not be present at boot time. If eth_initialize() doesn't detect the network and a net command is run the system crashes. This patch adds a function to cmd_net.c to check the availability of the ethernet device before trying to access it. If the net device is not found it will print a message and return -1.

* Add check to cmd_net functions to make sure ethernet device is valid before calling Net_Loop() Patch by Andrew Dyer, 24 Oct 2005
