Having ENA would still be good, as it should perform much better.
Given that it is split in two parts and the "common" ones should
only need cosmetical changes (like include paths and a few ifdefs
for NetBSD), the main work should not be that bad.

A volunteer to try this would need an amazon ec2 account with ENA (at
least I am not aware of any other platform using this spec currently).
