From 5f8629c526b4f7e529a6d27bbd802c0dc7fcc357 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20Miros=C5=82aw?= Date: Thu, 21 Apr 2011 13:59:21 +0000 Subject: [PATCH] net: fix hw_features ethtool_ops->set_flags compatibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit __ethtool_set_flags() was not taking into account features set but not user-toggleable. Since GFLAGS returns masked dev->features, EINVAL is returned when passed flags differ to it, and not to wanted_features. Signed-off-by: Michał Mirosław Signed-off-by: David S.
