Support for 10Gb Link using XGMAC core plus some performance tweaks.

Tested in a PCI based setup.

iperf3 TCP results:
	TSO ON, MTU=1500, TX Queues = 1, RX Queues = 1, Flow Control ON
	Pinned CPU (-A), Zero-Copy (-Z)

[ ID] Interval           Transfer     Bitrate         Retr

Series applied, thanks Jose.

About the Kconfig change, maybe it just doesn't make sense to list all
of the various speeds the chip supports... just a thought.

What about: "STMicroelectronics Multi-Gigabit Ethernet driver" ?

Or, just "STMicroelectronics Ethernet driver" ?

Maybe the first one is better, I don't know.  What are the chances of there
being more STMicroelectronics ethernet NICs? :-)
