Hi Stany, I haven't looked over it in detail, but a few little things anyway. On 21/08/12 22:18, Stany MARCEL wrote:

I would put your signed-off-by line here (with the --- separator). I would like to see the above text in the commit message.

We used to have this on the older FEC driver, but it is all removed now. I don't think we want this as a config option. Regards Greg
