Subject: [dpdk-dev] [PATCH v10 05/18] net/bnxt: check max SIMD bitwidth
Date: Mon, 19 Oct 2020 15:48:45 +0200
Message-ID: <20201019134858.32507-6-david.marchand@redhat.com> (raw)
In-Reply-To: <20201019134858.32507-1-david.marchand@redhat.com>

From: Ciara Power <ciara.power@intel.com>

When choosing a vector path to take, an extra condition must be
satisfied to ensure the max SIMD bitwidth allows for the CPU enabled
path.
