4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Alexandre Belloni <[email protected]> commit f505dba762ae826bb68978a85ee5c8ced7dea8d7 upstream. No interrupt were received from the phy because PIOE 1 may not be properly muxed. It prevented proper link detection, especially since commit 321beec5047a ("net: phy: Use interrupts when available in NOLINK state") disables polling.
