Two reasons:
 - I wasn't able to test all Intel PMD changes: 
   don't have a box with ixbe HW.
   Tested ice changes just a bit (test-pmd rx_only mode).
   In fact, there seems no that many use-cases for RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT.
 - I expect it will become part of greater VLA removal series:

That would be good, but right now I don't see any unit-tests  for it.
Have to do some manual testing with scapy+testpmd.  
I presume there are some GRO tests in DTS, but I never looked inside it so far.
