[dpdk-dev] [PATCH 0/3] add SA config option for inner pkt csum

[dpdk-dev] [PATCH 0/3] add SA config option for inner pkt csum

[Archana Muniganti]

Add inner packet IPv4 hdr and L4 checksum enable options
in conf. These will be used in case of protocol offload.
Per SA, application could specify whether the
checksum(compute/verify) can be offloaded to security device.

Depends on

New feature flag need to be added in
doc/guides/cryptodevs/features/default.ini As well.

Similarly it need to be updated in cn10k.ini file as well in the next patch.
