From f21105df0f999f468f1f03e1ff53fe055e149341 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 21 Aug 2012 11:45:08 -0700 Subject: [PATCH] netdev: octeon_mgmt: Improve ethtool_ops. Correctly show no link when the interface is down, and return -EOPNOTSUPP for things that don't work. This quiets the ethtool program when run on down interfaces.
