There are only three implementations of get_link_af_size, so please just simply change it's signature by adding the ext_filter_mask parameter instead of creating a completely new operation. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
