So, to make use of QEMU's netmap backend (CONFIG_NETMAP), you have to
build and install netmap software from sources. Which pretty much
ensures nobody uses it. It was added in commit 58952137b0b (Nov 2013).
The commit message points to <http://info.iet.unipi.it/~luigi/netmap/>,
which gives me "connection timed out" right now.
On the other hand, it's covered in MAINTAINERS, and has seen
non-janitorial activity as late as Dec 2018 (commit c693fc748a).
Luigi, Giuseppe, Vincenzo, what's the status of the netmap project?
Why is the QEMU netmap backend worth keeping?
Who is using the netmap backend?
How do they obtain a netmap-enabled QEMU? Compile it from sources
themselves?
Would it make sense to have netmap packaged in common Linux distros?
