-Date: Fri, 10 Jan 2020 15:38:38 +0530
-Subject: [PATCH 2/2] eng_devcrypto: add support for TLS1.2 algorithms offload
-
- - aes-128-cbc-hmac-sha256
- - aes-256-cbc-hmac-sha256
-
-Enabled the support of TLS1.1 algorithms offload
-
- - aes-128-cbc-hmac-sha1
- - aes-256-cbc-hmac-sha1
-
-Requires TLS patches on cryptodev and TLS algorithm support in Linux
-kernel driver.
-
-Fix: Remove the support for TLS1.0.
