It would be helpful if you could cite the git SHA1 for the commit. We're also having a conversation about the question of binding drivers to VFs on powerpc here: https://lkml.kernel.org/r/20170922140608.47665-3-bryantly@xxxxxxxxxxxxxxxxxx It's not exactly the same issue, but you might have useful input there.
