Please disregard these patches, somehow I failed to include all the changes and it fails to build. Sorry.
From: Ioana Ciornei <ioana.ciornei@nxp.com> The dpaa2-eth driver uses two indirect calls in fast-path, one invoked on each FD to consume the packet and one for each Tx packet to be enqueued. Use the indirect call wrappers infrastructure in both dpaa2-eth and dpaa2-switch drivers so that we avoid any RETPOLINE overhead.
