From 14004d1a4d4b5b155e1c94da222388167456c3cd Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 8 Nov 2005 12:24:23 -0800 Subject: [PATCH] ethtool: Format register dump for tg3 Format output of "ethtool -d" for tg3 devices to make it more readable. Each register is displayed as a 32-bit value and the undefined regions in the register space are skipped.
