Subject: [dpdk-dev] [PATCH v4 2/8] cryptodev: allocate max space for internal qp array
Date: Wed, 20 Oct 2021 16:57:48 +0530	[thread overview]
Message-ID: <20211020112754.1270163-3-gakhil@marvell.com> (raw)
In-Reply-To: <20211020112754.1270163-1-gakhil@marvell.com>

At queue_pair config stage, allocate memory for maximum
number of queue pair pointers that a device can support.

This will allow fast path APIs(enqueue_burst/dequeue_burst) to
refer pointer to internal QP data without checking for currently
configured QPs.
This is required to hide the rte_cryptodev and rte_cryptodev_data
structure from user.
