Hi Ferruh, 

No response from qede, ice and i40e. Basically the original queue
release api is shared by private queues(not registered to ethdev),
can't access by index, that why a warpper was there. To avoid more
rebase in last minute for this big patch, do you think we could close
it?

BTW, from feedback from hns3, I will post a new version to add the
macro.
