Hi Maxime

I think the idea is good. I just have a few English language
issues/questions.

Capabilities is more often used than abilities. I just wondered if
abilities is taken from the 802.3 specifications?

Also, i wonder if we should include _pma_ in the name? At some point
we might want to do something similar for other sublayers.
