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.
