From: Giuseppe Lettieri <giuseppe.letti...@unipi.it>
With this patch, netmap support can be enabled with
the following options to the configure script:
--enable-netmap[=system]
Use the host system netmap installation.
Fail if not found.
--enable-netmap=git
clone the official netmap repository on
github (mostly useful for CI)
