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.

Ioana Ciornei (3):
  dpaa2-eth: use indirect calls wrapper for FD enqueue
  dpaa2-eth: use indirect calls wrapper for FD consume
  dpaa2-switch: use an indirect call wrapper instead of open-coding

Please disregard these patches, somehow I failed to include all the
changes and it fails to build. Sorry.
