Ben, we were assuming this same issue would happen with the bridge. Do we know
if that's true? It seems like it would be a pretty serious problem as the
number of containers/VMs grows on a host, so I'm wondering what the kernel

Linux has an internal queue that temporarily holds packets transmitted to
certain network devices. If too many packets are transmitted to such
network devices within a single list of actions, then packets tend to get
dropped. Broadcast or flooded or multicast packets on bridges with
thousands of
