From f6878e39c726e13e1d0dfed863dcce81810e4a56 Mon Sep 17 00:00:00 2001 From: Akeem G Abodunrin Date: Wed, 28 Aug 2013 02:23:09 +0000 Subject: [PATCH] igb: Get speed and duplex for 1G non_copper devices This patch changes how we get speed/duplex for non_copper devices; it now uses pcs register to get current speed and duplex instead of using generic status register that we use to detect speed/duplex for copper devices.
