This also affects google containers and is related to the veth interface structure. So this doesn't affect PVE at all? Consider this:
"Our patch has been reviewed and accepted into the kernel, and is currently being backported to -stable releases back to 3.14 in different distributions (such as Suse, and Canonical)."
If this is docker-only what's SuSE doing with this then and why is the mainstream kernel taking patches?
