+  ====================================  ======  ==========================
+
+Request constains only one bitset which can be either value/mask pair (request
+to change specific feature bits and leave the rest) or only a value (request
+to set all features to specified set).
+
+As request is subject to netdev_change_features() sanity checks, optional
+kernel reply (can be suppressed by ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request
+header) informs client about the actual result. ``ETHTOOL_A_FEATURES_WANTED``
+reports the difference between client request and actual result: mask consists
+of bits which differ between requested features and result (dev->features
+after the operation), value consists of values of these bits in the request
+(i.e. negated values from resulting features). ``ETHTOOL_A_FEATURES_ACTIVE``
+reports the difference between old and new dev->features: mask consists of
+bits which have changed, values are their values in new dev->features (after
+the operation).
