I've built a package of pyroute2 with the increased DEFAULT_RCVBUF size of 32k and forwarded a patch to upstream.
Please try out the pyroute2 version in this https://launchpad.net/~billy-olsen/+archive/ubuntu/pyroute2-lp1904730
Additionally, another work around is to reduce the number of VFs from 64 to 32. Not a great work around, but should enable testing.
