    ikev2: for ECDSA add fallback to legacy ECDSA_SHA2_NNN_Pxxx authentication
    
    - like for RSA, only use Digital Signature ECDSA when peer sent
      N(SIGNATURE_HASH_ALGORITHMS)
    
    - as fallback, based on the local haso policy, magic up one of the
      ECDSA_SHA2_NNN_Pxxx authentication methods
    
      This code should really be making the decision based on the pubkey.
