We likely need to update versions for older branches too.
Might be done with a separate patch.  We need to maintain
this list at least on master branch since we have it in
documentation.

Sure, happy to update it in this patch, I've sent DPDK updates forbranches 2.9 - 2.13. I can wait for them to be approve before updating here?
