Merge branch 'dpaa2-eth-sw-TSO'

Ioana Ciornei says:

====================
dpaa2-eth: add support for software TSO

This series adds support for driver level TSO in the dpaa2-eth driver.

The first 5 patches lay the ground work for the actual feature:
rearrange some variable declaration, cleaning up the interraction with
the S/G Table buffer cache etc.

The 6th patch adds the actual driver level software TSO support by using
the usual tso_build_hdr()/tso_build_data() APIs and creates the S/G FDs.

With this patch set we can see the following improvement in a TCP flow
running on a single A72@2.2GHz of the LX2160A SoC:

before: 6.38Gbit/s
after:  8.48Gbit/s
