Subject: [dpdk-stable] [PATCH v3 4/5] net/mlx5: fix RSS RETA update
Date: Wed, 29 Sep 2021 11:17:00 +0200
Message-ID: <20210929091701.158047-5-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20210929091701.158047-1-maxime.coquelin@redhat.com>

This patch fixes RETA updating for entries above 64.
Without ithat, these entries are never updated as
calculated mask value will always be 0.

Fixes: 634efbc2c8c0 ("mlx5: support RETA query and update")
Cc: stable@dpdk.org
Cc: nelio.laranjeiro@6wind.com
