Octeontx PMD driver has no dependency in general (on other octeontx patch series),
except one external mempool api.. coming in from series ,
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  has direct dependency on ,.
and those dependency series akced and planned to get merged into -rc1 release.
