As of now unfortunately we do not have spare cycles to perform the
upgrade (that may change, but I prefer not to commit to any timeframe
whatsoever). Between 11.2 and HEAD there was a big contrib
(sys/contrib/ncsw/) part update and our changes, using the latest
common code from NXP are conflicting to a great extent.

Yes, briefly - the DPAA2 is more complex than its predecessor and it
should be added from scratch, so it seems much more work to introduce
the support for the NIC from the LX2K SoCs.
