AQR113c does not correctly report its supported PMA
capabilities which includes speeds like 10G/5G/2.5G.
Add get_features() to explicitly declare 10G/5G/2.5G/1G
support instead of relying on PMA register reads.

Please slow down. You need to let discussions about previous versions
come to a conclusion.
