FreeBSD/EC2 users: Please test new ENA driver

[Colin Percival]

If you use FreeBSD in EC2 and you care about network performance, you have
about 3 days to test the ENA (Amazon 2nd generation "enhanced networking")
driver in 11.1-RC2 before it's too late to get bugs fixed.  AMI numbers are
in the announcement:

https://lists.freebsd.org/pipermail/freebsd-stable/2017-July/087369.html

The ENA driver is enabled automatically in the instance types with that
hardware (m4.16xlarge and F1, I3, P2, R4, X1 family instance types), so the
only difference you should notice is that you get lower CPU usage, lower
latency, and more throughput than the Xen netfront driver provided.
