Is there a basic recipe available for building even a 2-port VALE bridge with netmap (igb) interfaces, with perhaps some output (log entries, etc.) to validate that the configuration is behaving as expected? We get lots of log messages that seem good, as well as many whose meaning is unclear (they only appear with "verbose" set, but seem to indicate unexpected happenings), and we see packets enter the bridge and the learning loop executed (although unfortunately there doesn't seem to be any way to inspect the current state of the FIB), but no packets actually egress from the device. Thanks, Nick
