   4 Subject: [[Patch][fsl 01/16] add support for composite TLS(SHA1,AES)
   5  algorithm offload
   6
   7 Upstream-status: Pending
   8
   9 This adds support for composite algorithm offload in a single crypto
  10 (cipher + hmac) operation.
  11
  12 It requires either software or hardware TLS support in the Linux kernel
  13 and can be used with Freescale B*, P* and T* platforms that have support
  14 for hardware TLS acceleration.
