Re: ethernet patch for kernel 2.6 for ml403

["David H. Lynch Jr." <dhlii@dlasys.net>]

    I have used a later version of what I beleive is the same patch.
            http://source.mvista.com/~ank/paulus-powerpc/20060309/

    This is for the PLB TEMAC. My guess based on your capture below is 
that you are using that IP.
  
    Did you try ifconfig eth0 xxx.xxx.xxx.xxx ?
    I do not know what is in the rest of your init setup but something 
must asign the IP and bring up the interface.
