   4 Subject: [PATCH 17/48] eng_cryptodev: add support for TLSv1.2 record offload
   5
   6 Supported cipher suites:
   7 - 3des-ede-cbc-sha
   8 - aes-128-cbc-hmac-sha
   9 - aes-256-cbc-hmac-sha
  10 - aes-128-cbc-hmac-sha256
  11 - aes-256-cbc-hmac-sha256
  12
  13 Requires TLS patches on cryptodev and TLS algorithm support in Linux
  14 kernel driver.
