From 109115e1991824b88306b374b763d6857b292aeb Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Fri, 2 May 2008 16:48:59 -0700 Subject: [PATCH] tg3: Fix ethtool loopback test for 5761 BX devices A CPMU related loopback test bug existed for AX revisions of the 5761. While that errata has been fixed, the CPMU still slows down the core clock too far to run the loopback test successfully. This patch disables the CPMU LINK_SPEED mode just like we do with the AX revisions of the 5761 and all revisions of the 5784.
