[dpdk-dev] [PATCH v2 1/4] ethdev: fix integrity flow item

[Gregory Etelson <getelson@nvidia.com>]

Add integrity item definition to the rte_flow_desc_item array.
The new entry allows to build RTE flow item from a data
stored in rte_flow_item_integrity type.

Add bitmasks to the integrity item value.
The masks allow to query multiple integrity filters in a single
compare operation.

Fixes: b10a421a1f3b ("ethdev: add packet integrity check flow rules")
