Subject[PATCH 4.14 051/110] net: phy: fix phy_start to consider PHY_IGNORE_INTERRUPT
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Heiner Kallweit <hkallweit1@gmail.com>


[ Upstream commit 08f5138512180a479ce6b9d23b825c9f4cd3be77 ]

This condition wasn't adjusted when PHY_IGNORE_INTERRUPT (-2) was added
long ago. In case of PHY_IGNORE_INTERRUPT the MAC interrupt indicates
also PHY state changes and we should do what the symbol says.
