A set of RSS fixes and improvements for the dpaa2 PMD. Patches 1 and 2 fix the RSS hash key: the L4 destination port was never added (both extracts used the source port), and SCTP now uses the same L4 port extraction as TCP/UDP. Both are tagged for stable.
Patches 3 and 4 are small cleanups in the key builder (a dead num_extracts increment, and the unset PPPoE guard flag). Patch 5 honours RTE_ETH_RSS_LEVEL_INNERMOST so tunnelled traffic hashes on the inner IP header. Patch 6 implements reta_query / reta_update as an emulation over the HW distribution-size mechanism, since dpaa2 has no software-visible indirection table. Tested on LX2160A (lx2160acex7).
