Subject: [dpdk-dev] [PATCH 18/37] bus/dpaa: add shared MAC support
Date: Wed, 27 May 2020 18:53:07 +0530
Message-ID: <20200527132326.1382-19-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <20200527132326.1382-1-hemant.agrawal@nxp.com>

From: Radu Bulie <radu-andrei.bulie@nxp.com>

A shared MAC interface is an interface which can be used
by both kernel and userspace based on classification configuration
It is defined in dts with the compatible string "fsl,dpa-ethernet-shared"
which bpool will be seeded by the dpdk partition and configured
as a netdev by the dpaa Linux eth driver.
User space buffers from the bpool will be kmapped by the kernel.
