Thanks Cyril and Michael, It works. Now I have the patch ready for Ethernet and NFS for Hawkboard in the latest rc. I have tested with ifconfig, ping and mounting a FS by NFS. Caglar the patch is different form your patch in [1], would be OK if I submit it ? I have attached my patch please tell me if it is ok for you if i send the patch, I have been working with all the other patches for complete support but always with the latest rc. except for USB. Thanks for all Sincerely yours Victor Rodriguez [1] http://gitorious.org/linux-davinci-hawk/linux-davinci-hawk/commit/3712194f2e674cc46cc076cb009c2530b4d46a63
