Subject: [RFC v1 1/7] net/mlx5: add LWM support for Rxq
Date: Fri, 6 May 2022 06:56:39 +0300	[thread overview]
Message-ID: <20220506035645.4101714-2-spiked@nvidia.com> (raw)
In-Reply-To: <20220506035645.4101714-1-spiked@nvidia.com>

Add lwm(Limit WaterMark) field to Rxq object which indicates the percentage
of RX queue size used by HW to raise LWM event to the user.
Allow LWM setting in modify_rq command.
Allow the LWM configuration dynamically by adding RDY2RDY state change.
