So what do we do in DPDK?
Do you agree with the patch I sent to correct wrong assumptions
in the doc?
My fear is that if we keep mana PMD as-is,
it could break compilation when libmana will be released
if there is an incompatibility with what you have in staging.
Please remember that rdma-core is also used for mlx PMDs,
and we don't want mana to break compilation when updating rdma-core.
