[dpdk-dev] [PATCH 41/44] net/cnxk: add initial version of rte flow support

[Nithin Dabilpuram <ndabilpuram@marvell.com>]

From: Kiran Kumar K <kirankumark@marvell.com>

Adding initial version of rte_flow support for cnxk family device.
Supported rte_flow ops are flow_validate, flow_create, flow_crstroy,
flow_flush, flow_query, flow_isolate.
