net/sched: taprio: replace tc_taprio_qopt_offload :: enable with a "cmd" enum
Inspired from struct flow_cls_offload :: cmd, in order for taprio to be able to report statistics (which is future work), it seems that we need to drill one step further with the ndo_setup_tc(TC_SETUP_QDISC_TAPRIO) multiplexing, and pass the command as part of the common portion of the muxed structure. Since we already have an "enable" variable in tc_taprio_qopt_offload, refactor all drivers to check for "cmd" instead of "enable", and reject every other command except "replace" and "destroy" - to be future proof.
