Subject: net: phy: Allow EEE for all RGMII variants
From: Florian Fainelli <[email protected]>
[ 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.
Fixes: a59a4d192166 ("phy: add the EEE support and the way to access to the MMD
registers")
