[dpdk-dev] [PATCH v2 02/10] cryptodev: add digest encrypted feature flag

[Damian Nowak <damianx.nowak@intel.com>]

Some PMDs can only support digest being
encrypted separately in auth-cipher operations.
Thus it is required to add feature flag in PMD
to reflect if it does support digest-appended
both: digest generation with encryption and
decryption with digest verification.
