From 76fd85937097a0c2ec8ab23bf21dc10992d1c398 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Fri, 8 Sep 2006 11:16:13 -0700 Subject: [PATCH] ethtool: allow const ethtool_ops The ethtool_ops structure is immutable, it expected to be setup by the driver and is never changed. This patch allows drivers to declare there ethtool_ops structure read-only.
