--- Comment #23 from pete at nomadlogic.org ---
I have a c5.large ec2 instance i'm running to test this using 12.0-ALPHA5.  In
the same VPC I have a system using a xn ethernet interface.  I am running
iperf3 between these two systems and getting just shy of 1Gbs network
throughput, and ~13Kp/s.

The c5.large system with ena interfaces has not had any problems so far.  I've
run several iperf3 TCP tests for 10mins each with no errors.  As mentioned
earlier, the interface flapping errors have gone away as well.

If there are other artificial benchmarks that I should run to help validate
this configuration has stabilized let me know and I can run them today.
