[PATCH net-next 02/15] ixgbe: E610: update EEE supported speeds

[Jacob Keller]

From: Jedrzej Jagielski <jedrzej.jagielski@xxxxxxxxx>

Despite there was no EEE (Energy Efficient Ethernet) feature
support for E610 adapters, eee_speeds_supported variable was
defined and even initialized with some EEE speeds.

As E610 adapter supports EEE only for 10G, 5G and 2.5G speeds,
update hw.phy.eee_speeds_supported. Remove unsupported speeds -
10M, 100M and 1G.

Add also entry for 5G speed in EEE speeds mapping array used
by ethtool callbacks.
