Aleksandr Loktionov 0568ee1198 i40e: Add Energy Efficient Ethernet ability for X710 Base-T/KR/KX cards
Add "EEE: Enabled/Disabled" to dmesg for supported X710 Base-T/KR/KX
cards. According to the IEEE standard report the EEE ability and the
EEE Link Partner ability. Use the kernel's 'ethtool_keee' structure
and report EEE link modes.

Example:
dmesg | grep 'NIC Link is'
ethtool --show-eee <device>

Before:
	NIC Link is Up, 10 Gbps Full Duplex, Flow Control: None

        Supported EEE link modes:  Not reported
        Advertised EEE link modes:  Not reported
        Link partner advertised EEE link modes:  Not reported

After:
	NIC Link is Up, 10 Gbps Full Duplex, Flow Control: None, EEE: Enabled

        Supported EEE link modes:  100baseT/Full
                                   1000baseT/Full
                                   10000baseT/Full
        Advertised EEE link modes:  100baseT/Full
                                    1000baseT/Full
                                    10000baseT/Full
        Link partner advertised EEE link modes:  100baseT/Full
                                                 1000baseT/Full
                                                 10000baseT/Full

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
