   4 Subject: [PATCH 1/9] add support for composite TLS10(SHA1,AES) algorithm
   5  offload
   6
   7 This adds support for composite algorithm offload as a primitive
   8 crypto (cipher + hmac) operation.
   9
  10 It requires kernel support for tls10(hmac(sha1),cbc(aes)) algorithm
  11 provided either in software or accelerated by hardware such as
  12 Freescale B*, P* and T* platforms.
