Subject: [dpdk-stable] [PATCH 1/5] net/mlx5: fix unused calculation in RSS expansion
Date: Wed, 11 Nov 2020 07:36:44 +0000
Message-ID: <1605080208-12165-1-git-send-email-michaelba@nvidia.com> (raw)

The RSS flow expansion get a memory buffer to fill the new patterns of
the expanded flows.
This memory management saves the next address to write into the buffer
in a dedicated variable.

The calculation for the next address was wrongly also done when all the
patterns were ready.

Remove it.

Fixes: 4ed05fcd441b ("ethdev: add flow API to expand RSS flows")
Cc: stable@dpdk.org
