Octeontx PMD driver has no dependency in general (on other octeontx patch series), 
except one external mempool api.. coming in from series [1], 
and that api will remain unchanged as its octeon specific. 
So having said that, You can start reviewing and sharing
feedback to us.

Note: octeontx external mempool pmd [1] has direct dependency on [2],[3].[4]
and those dependency series akced and planned to get merged into -rc1 release.
