Ah! yes checkpatch was preempting me to use ARRAY_SIZE I forgot RTE_DIM exists.

Makes sense, as it would probably break if future updates to ptype_masks 
are not added to the above list. 

I will roll a v11.

Thanks,

* [dpdk-dev]  [PATCH v9 0/7] ethdev: add new Rx offload flags
@ 2019-10-07  6:51 pbhagavatula
  2019-10-09 15:33 ` [dpdk-dev] [PATCH v10 " pbhagavatula

  To: arybchenko, jerinj; +Cc: dev, Pavan Nikhilesh

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Add new Rx offload flags `DEV_RX_OFFLOAD_RSS_HASH` and
`DEV_RX_OFFLOAD_FLOW_MARK`. These flags can be used to
enable/disable PMD writes to rte_mbuf fields `hash.rss` and `hash.fdir.hi`
and also `ol_flags:PKT_RX_RSS` and `ol_flags:PKT_RX_FDIR`.

Add new packet type set function `rte_eth_dev_set_supported_ptypes`,
allows application to inform PMDs about the packet types it is interested
in. Based on ptypes requested by application PMDs can optimize the Rx path.

For example, if a given PMD doesn't support any packet types that the
application is interested in then the application can disable[1] writes to
`mbuf.packet_type` done by the PMD and use a software ptype parser.
     [1] rte_eth_dev_set_supported_ptypes(*port_id*, RTE_PTYPE_UNKNOWN, NULL,
                                          0);

v9 Changes:
----------
- Add ptype_mask validationin set_supported_ptypes.(Andrew)
- Make description more verbose.

v8 Changes:
----------
- Make description more verbose.
- Set RTE_PTYPE_UNKNOWN in set_ptypes array when either get ot set ptypes
  is not supported by ethernet device.

v7 Changes:
----------
- Fix unused variable in net/octeontx2

v6 Changes:
----------
- Add additional checks for set supported ptypes.(Andrew)
- Clarify `rte_eth_dev_set_supported_ptypes` documentation.
- Remove DEV_RX_OFFLOAD_FLOW_MARK emulation from net/octeontx2.

v5 Changes:
----------
- Fix typos.

v4 Changes:
----------
- Set the last element in set_ptype array as RTE_PTYPE_UNKNOWN to mark the end
  of array.
- Fix invalid set ptype function call in examples.
- Remove setting rte_eth_dev_set_supported_ptypes to UNKNOWN in l3fwd-power.

v3 Changes:
----------
- Add missing release notes. (Andrew)
- Re-word various descriptions.
- Fix ptype set logic.

v2 Changes:
----------
- Update release notes. (Andrew)
- Redo commit logs. (Andrew)
- Disable ptype parsing for unsupported examples. (Jerin)
- Disable RSS write only in generic mode eventdev_pipeline. (Jerin)
- Modify set_supported_ptypes function to return successfuly set mask
  instead of failure.
- Dropped set_supported_ptypes to drivers by handling in library
  layer, interested PMD can add it in.


Pavan Nikhilesh (7):
  ethdev: add set ptype function
  ethdev: add mbuf RSS update as an offload
  ethdev: add flow action type update as an offload
  drivers/net: update Rx RSS hash offload capabilities
  drivers/net: update Rx flow flag and mark capabilities
  examples/eventdev_pipeline: add new Rx RSS hash offload
  examples: disable Rx packet type parsing
