phylib: Add interrupt source check function to M88E1121R driver (dcd07be3) · Commits · 戴 / test

Add did_interrupt() function to check if a PHY port really caused an interrupt. This is needed in the case of shared PHY interrupt pin configuration to stop interrupt event processing for PHY ports which didn't cause an interrupt. Signed-off-by:
