3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Florian Fainelli <f.faine...@gmail.com> [ Upstream commit 7e14069651591c81046ffaec13c3dac8cb70f5fb ] RGMII interfaces come in multiple flavors: RGMII with transmit or receive internal delay, no delays at all, or delays in both direction. This change extends the initial check for PHY_INTERFACE_MODE_RGMII to cover all of these variants since EEE should be allowed for any of these modes, since it is a property of the RGMII, hence Gigabit PHY capability more than the RGMII electrical interface and its delays.
