From 6980ffa0c5a8e65d53ff803d2cafdba3e2022714 Mon Sep 17 00:00:00 2001 From: Tariq Toukan Date: Sun, 21 Jun 2020 21:35:34 +0300 Subject: net/mlx5e: RX, Add checks for calculated Striding RQ attributes Striding RQ attributes below are mutually dependent. An unaware change to one might take the others out of the valid range derived by the HW caps: - The MPWQE size in bytes - The number of strides in a MPWQE - The stride size Add checks to verify they are valid and comply to the HW spec and SW assumptions/requirements. This is not a fix, no particular issue exists today.

During stress this QP is competing on the HW resources with all the other QPs that are used to send data. To protect SW steering QP's performance in such cases, we set this QP to use isolated VL. The VL number is reserved by FW and is not exposed to the driver. Support for this QP on isolated VL exists only when both force-loopback and isolate_vl_tc capabilities are set.
