Apologies, yes, we missed this in the changelog.
For the change itself, if we are removing the need for RTE_PTYPE_UNKNOWN in the supported ptypes lists to mark the last element, do we still need to add it here when setting ptypes list?
Maybe a misunderstanding on my part - I thought it would be the same for both cases.
Thanks,
Ciara
