Subject[PATCH 4.19 07/47] net: thunderx: start phy before starting autonegotiation
Date
From: Mian Yousaf Kaukab <ykaukab@suse.de>

[ Upstream commit a350d2e7adbb57181d33e3aa6f0565632747feaa ]

Since commit 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.

As phy_start() takes care of calling phy_start_aneg(), drop the explicit
call to phy_start_aneg().

Network fails without this patch on Octeon TX.
