[PATCH AUTOSEL 4.14 130/130] net: phy: initialise phydev speed and duplex sanely
From: Sasha Levin

From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx>
[ Upstream commit a5d66f810061e2dd70fb7a108dcd14e535bc639f ]
When a phydev is created, the speed and duplex are set to zero and
-1 respectively, rather than using the predefined SPEED_UNKNOWN and
DUPLEX_UNKNOWN constants.
There is a window at initialisation time where we may report link
down using the 0/-1 values. Tidy this up and use the predefined
constants, so debug doesn't complain with:
"Unsupported (update phy-core.c)/Unsupported (update phy-core.c)"
when the speed and duplex settings are printed.
