> The failsafe, bonding, and netvsc PMD use eth dev port ownership to control

> This patch set introduces a helper function to check if a port is under
> ownership. And the follow on patches use that.

> handle the case if secondary process exits prematurely without releasing
> ownership. It makes more sense to keep the concept of ownership as strictly
