I already added the phylib supporting and ethtool carrier detection in fec.c driver. Here is my git tree containing those patches: kernel. ubuntu. com/git? p=roc/ubuntu- lucid.git; a=shortlog; h=refs/ heads/fec; pg=0

Please find my kernel package here for testing: people. canonical. com/~roc/ kernel/ fec/
