[dpdk-dev] [PATCH v6 06/13] net/i40e: support ipsec-ah profile

[Bernard Iremonger <bernard.iremonger@intel.com>]

Add flow structures for the following patterns in i40e_ethdev files:
eth/ipv4/esp
eth/ipv6/esp
eth/ipv4/udp/esp
eth/ipv6/esp/udp

add oip_type in filter
add is_udp in filter
use tenant_id in filter for spi
