[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. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
