Hi Rosen,
This is the bus code, and only drivers will call it right? I think there is no
intention to make this run by application code, the functions need to be
exported because driver and bus are different libraries.
If above correct, there is no point of making the function experimental, can
drop the __rte_experimental tag, and update .map file to not use EXPERIMENTAL.
