4.15-stable review patch.  If anyone has any objections, please let me know.


From: Heiner Kallweit <hkallwe...@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.
