Add new Rx offload flag `DEV_RX_OFFLOAD_FLOW_MARK` that can be used to
enable/disable PMDs write to `rte_mbuf::hash::fdir::hi`.
Notes similar to RSS hash.
It requires better motivation why. It lets Rx queue know that
it will be used as flow action MARK target and the queue should
be configured to deliver the mark from NIC to PMD and processed
in the driver.
Also I think that flow API action MARK documentation should be
updated to mentioned the offload.
