From c6700ce2248ecf3b1b6fd009f6aed9b6387d3377 Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Mon, 13 Feb 2012 15:20:15 +0000 Subject: tg3: Remove unneeded link_config.orig_... members This patch removes the unneeded link_config.orig_* members. When the phy is in a low power state, the TG3_PHYFLG_IS_LOW_POWER flag solely determines how the link is configured. When the phy is powered back up, it can resume using the original settings. For the phylib case, the link configuration still needs to be saved, but since the phylib maintains its own configuration, we can repurpose the (unused in this case) tg3 link configuration members.
