From 321beec5047af83db90c88114b7e664b156f49fe Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Mon, 16 Nov 2015 23:36:46 +0100 Subject: [PATCH] net: phy: Use interrupts when available in NOLINK state The NOLINK state will poll the phy once a second to see if the link has come up. If the phy has an interrupt line, this polling can be skipped, since the phy should interrupt when the link returns. Signed-off-by: Andrew Lunn Signed-off-by: David S.
