   4 Subject: [PATCH 10/15] add support for composite TLS10(SHA1,3DES) algorithm
   5  offload
   6
   7 This adds support for composite algorithm offload in a single crypto
   8 (cipher + hmac) operation.
   9
  10 It requires either software or hardware TLS support in the Linux kernel
  11 and can be used with Freescale B*, P* and T* platforms that have support
  12 for hardware TLS acceleration.
