[Soekris] net4501 long ethernet cable problem

Linux kernel 2.4.20 does not have this option. But, kernel 2.4.18 does
have. I have not looked at the code of natsemi yet. I would like to use
the older driver in the later kernel. I am hoping to prepare a patch for
that. Am I on the right track?

Thanks for your help!
