From 9cb35bf6b6b2b7460d6e4a0fdfeeb70ec618044e Mon Sep 17 00:00:00 2001
From: Andrew Lunn <andrew@lunn.ch>
Date: Wed, 12 Sep 2018 01:53:15 +0200
Subject: [PATCH 0607/2940] net: ethernet: Add helper for MACs which support
asym pause
Rather than have the MAC drivers manipulate phydev members to indicate
they support Asym Pause, add a helper function.
