Kernel Oops when receiving a lot of UDP packets while booting

Montevista hardhat linux 2.0.  A couple of days ago someone had an
ethernet question about that, and I was confused.

Check to make sure that ethernet packet reception is disabled when you
leave the init() function, and doesn't get enabled until the _open()
function is called.  You might have to actually do work to disable it if
the bootloader already enabled things...

First you could use some flags and printks to see whether the crash is
really due to early packets, as I suspect.
