I use FromDevice in Linux 2.4.20 kernel, and my cpu usage is also
100% always. I even checked out the newest Click from the CVS
tonight. It's the same.

I have two Ethernet cards. Both of them are Realtek RTL8139. 
At the bottom of this email is my configuration file which was generated
by make-ip-conf.pl

Can anyone tell me what's wrong?

Thanks a lot.
