Subject: [PATCH] net: thunderx: start phy before starting autonegotiation
Date: Wed, 4 Dec 2019 16:26:51 +0100 [thread overview]
Message-ID: <20191204152651.13418-1-ykaukab@suse.de> (raw)
Since "2b3e88ea6528 net: phy: improve phy state checking"
phy_start_aneg() expects phy state to be >= PHY_UP. Call phy_start()
before calling phy_start_aneg() during probe so that autonegotiation
is initiated.
Network fails without this patch on Octeon TX.
