New Asymmetric Crypto Algorithm in DPDK - EdDSA
summary
DPDK adds EdDSA support (Ed 25519 and Ed 448) with curve IDs 29 and 30 and RFC 8032 test vectors validated by auto tests. New crypto-session enums, Ed-specific parameters and an asymmetric flag for compressed public key enable pubkey-gen, sign and verify via the existing crypto-op API (session transform, Pub_Key_Generate op, sign/verify ops). Implementation is deterministic (no nonce), resists side-channel timing/cache attacks, and shows ~30% faster signing with hardware offload and ~12% faster verification versus ECDSA; software TLS handshake performance is comparable.
