[PATCH] net: thunderx: start phy before starting autonegotiation
From: Mian Yousaf Kaukab
Date: Wed Dec 04 2019 - 10:26:05 EST
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.
