From: Abhinandan Gujjar Date: Mon, 16 Apr 2018 06:54:54 +0000 (+0530) Subject: cryptodev: set private data for session-less mode X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=54c836846603188bef3c7b65d0a9d9a9167afb72;p=dpdk.git cryptodev: set private data for session-less mode The application may want to store private data along with the rte_crypto_op that is transparent to the rte_cryptodev layer. For e.g., If an eventdev based application is submitting a crypto session-less operation and wants to indicate event information required to construct a new event that will be enqueued to eventdev after completion of the crypto operation. This patch provides a mechanism for the application to associate this information with the rte_crypto_op in session-less mode.
