Subject: [06/21] ehea: fix wrongly reported speed and port

2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------

From: Kleber Sacilotto de Souza <klebers@...ux.vnet.ibm.com>

commit dcbe14b91a920657ff3a9ba0efb7c5b5562f956a upstream.

Currently EHEA reports to ethtool as supporting 10M, 100M, 1G and
10G and connected to FIBRE independent of the hardware configuration.
However, when connected to FIBRE the only supported speed is 10G
full-duplex, and the other speeds and modes are only supported
when connected to twisted pair.
