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. -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
