Subject: [PATCH net-next 07/11] net: dsa: mv88e6xxx: call phy_init_eee
Date: Mon, 31 Jul 2017 18:17:15 -0400	[thread overview]
Message-ID: <20170731221719.16695-8-vivien.didelot@savoirfairelinux.com> (raw)
In-Reply-To: <20170731221719.16695-1-vivien.didelot@savoirfairelinux.com>

It is safer to init the EEE before the DSA layer call
phy_ethtool_set_eee, as sf2 and qca8k are doing.
