[dpdk-dev] [RFC 1/7] ethdev: add device ipsec encrypt/decrypt capability flags

[Boris Pismenny <borisp@mellanox.com>]

A PMD that presents these flags supports IPsec crypto offload.
Encryption and authentication on SA entries can be offloaded to
the PMD. After adding a SA to hardware, crypto can be offloaded
on well-formed IPsec packets.
