From: Nikolay Aleksandrov <[email protected]> When __netdev_update_features() was updated to ensure some features are disabled on new lower devices, an error was introduced for devices which don't have the ndo_set_features() method set. Before we'll just set the new features, but now we return an error and don't set them. Fix this by returning the old behaviour and setting err to 0 when ndo_set_features is not present.

This makes the 'err' initializer pointless. MBR, Sergei -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
