From cc80ee13609dc5926ad563d1a793991c80675e65 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Tue, 29 Apr 2014 12:56:21 -0500 Subject: [PATCH] net: stmmac: set phy to use polling by default mii_irq[] array is never initialized anywhere in the driver, thus mii_irq[] will always equate to zero. So, for the case where the PHY does not have an irq, we should use PHY_POLL for that situation. Signed-off-by: Dinh Nguyen Tested-by: Vince Bridgers Signed-off-by: David S.
