-* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic
- definition in line with the ethdev TM and MTR APIs. Currently, this field
- is defined in librte_sched in a non-generic way. The new generic format
- will contain: queue ID, traffic class, color. Field size will not change.

-* sched: Some API functions will change prototype due to the above
- deprecation note for mbuf->hash.sched, e.g. ``rte_sched_port_pkt_write()``
- and ``rte_sched_port_pkt_read()`` will likely have an additional parameter
- of type ``struct rte_sched_port``.

* mbuf: the macro ``RTE_MBUF_INDIRECT()`` will be removed in v18.08 or later and
