Subject: [PATCH net v2] net: thunderx: start phy before starting
autonegotiation
Patch-mainline: 5.5-rc1
Git-commit: a350d2e7adbb57181d33e3aa6f0565632747feaa
References: bsc#1158107 bnc#1151927 5.3.18
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.
Fixes: 2b3e88ea6528 ("net: phy: improve phy state checking")
