From 1be52e97ed3e524f82e25d6e53f48df3c6e85282 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 8 Aug 2018 20:56:40 +0200 Subject: [PATCH] dsa: slave: eee: Allow ports to use phylink For a port to be able to use EEE, both the MAC and the PHY must support EEE. A phy can be provided by both a phydev or phylink. Verify at least one of these exist, not just phydev.
