How is this different then calling the fdb op from rtnetlink.c when the NTF_SELF bit is set after your previous patch net: generic fdb support for drivers without ndo_fdb_<op> the generic routine gets called if a specific op is not supplied via ndo ops anyways right? Also I suspect if the driver supplies a specific ndo_fdb_<op> we should use it over the generic one. What am I missing? Thanks, John -- John Fastabend Intel Corporation
