Subject: [dpdk-dev] [PATCH 3/4] doc: add a decsription for MPRQ stride size devarg
Date: Tue, 31 Mar 2020 21:52:38 +0000 [thread overview]
Message-ID: <1585691559-17409-4-git-send-email-akozyrev@mellanox.com> (raw)
In-Reply-To: <1585691559-17409-1-git-send-email-akozyrev@mellanox.com>
Provide a descriptin of a newly added mprq_log_stride_size devarg
parameter for specifying a stride size in case of MPRQ Rx is on.
