[dpdk-dev] [PATCH 6/9] cryptodev: add digest encrypted feature flag

From: Damian Nowak <damianx.nowak at 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.
