The default-off decision was taken at the time when netmap was merged
in (see the
"[PATCH v3] net: Adding netmap network backend" thread).
The qemu ./configure already has support for probing netmap headers,
so we could actually switch to default-on also on linux (like it
happens for freebsd qemu build).

Thanks for the pointer to the headers. Any

No idea, unfortunately. I personally maintain an AUR package for
Archlinux (https://aur.archlinux.org/packages/netmap/), that's all I
know. Having netmap headers packaged in some distributions is
something we were willing to do, but still nothing has been done,
afaik.
