> Add AES-GMAC (RTE_CRYPTO_AUTH_AES_GMAC) support to the dpaa2_sec
> driver
> for both symmetric auth-only and IPsec lookaside protocol paths.
>
> For the auth-only path, AES-GMAC uses the GCM shared descriptor
> (cnstr_shdsc_gcm_encap/decap) with per-packet IV and data supplied
> via sym_op->auth.{iv,data,digest}.
>
> For the IPsec lookaside protocol path, AES-GMAC maps to
> OP_PCL_IPSEC_AES_NULL_WITH_GMAC. The SEC hardware protocol word
> treats this as a cipher type, so the GMAC key and algtype are placed
> in cipherdata rather than authdata. This is handled in
> dpaa2_sec_ipsec_proto_init() by overriding cipherdata with the auth
> key and setting authdata algtype to HMAC_NULL.
>
> Also add AES-GMAC to dpaa2_sec_capabilities[] as an AUTH xform.
