... it might have happened due to the removal of the "slirp" submodule from
the git repository. For example if you see an error message like this:
Parameter 'type' expects a netdev backend type
this likely means that the "user" mode backend type is not available in your
binary anymore. To fix it, simply install "libslirp-devel" (or libslirp-dev
or however it is called) from your OS distribution and recompile.
