From e875093c9659d2a9f3923aa9ee1b89ef40cf95b9 Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Mon, 12 Nov 2007 21:11:51 -0800 Subject: [PATCH] [TG3]: CPMU adjustments for loopback tests This patch adds the LINK_SPEED mode to the list of CPMU modes that can cause the loopback tests to fail. These bugs are planned to be fixed in future revisions of the chip, so the patch qualifies the fixes as such. Signed-off-by: Matt Carlson Signed-off-by: Michael Chan Signed-off-by: David S.
