Clark Boylan f93a3171ff Dynamically determine overlay MTU ... Some clouds we run on no longer have MTUs of 1500 on their interfaces and are smaller. We dynamically determine the MTU we should use on the overlay networks. List all "real" interfaces with a permament mac addr then use the smallest MTU less 50 bytes for vxlan overhead. We only consider "real" interfaces so that we can run this multiple times for separate overlays without perpetually decreasing the MTU due to finding the lower MTU we just configured.
