Subject: [dpdk-dev] [PATCH v3 2/4] common/qat: move max inflights param into qp
Date: Wed, 11 Dec 2019 15:50:02 +0100
Message-ID: <20191211145004.11672-3-arkadiuszx.kusztal@intel.com> (raw)
In-Reply-To: <20191211145004.11672-1-arkadiuszx.kusztal@intel.com>

From: Fiona Trahe <fiona.trahe@intel.com>

The max_inflights parameter is moved from qat_queue to qat_qp as it's
a more appropriate location.
