In this case the function will return -1 unless the environment is unset first
(using ``rte_power_unset_env``). Other function usage scenarios will not change.

+* ethdev: New offload flags ``DEV_RX_OFFLOAD_PTYPE``, ``DEV_RX_OFFLOAD_RSS_HASH``
+ and ``DEV_RX_OFFLOAD_FLOW_MARK`` will be added in 19.11.
+ This will allow application to enable or disable PMDs from updating
+ ``rte_mbuf`` fields ``rte_mbuf::packet_type``, ``rte_mbuf::hash::rss`` and
+ ``rte_mbuf::hash::fdir`` respectively.
+ This scheme will allow PMDs to avoid writes to ``rte_mbuf`` fields on Rx and
+ thereby improve Rx performance if application wishes do so.
+ In 19.11 PMDs will still update the fields even when the offloads are not
+ enabled.
+ The exact semantics of the flags will be worked out later either by making
+ them negative offloads to avoid application change or positive offload to
+ align with existing offload flag semantics.
