Origin: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit?id=84da60070c36ddcd8bf4a576e637be8e86535ede
Bug-Debian: https://bugs.debian.org/993948

commit 52ce14c134a003fee03d8fc57442c05a55b53715 upstream.

This function is called to enable SR-IOV when available,
not enabling interfaces without VFs was a regression.
