From: Radu Bulie Date: Fri, 4 Sep 2020 08:39:26 +0000 (+0530) Subject: bus/dpaa: support shared MAC X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=133332f01d91aef2056cbdc407f3fd3d61b24b83;p=dpdk.git bus/dpaa: support shared MAC 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.
