Hmm - here you use $with_virtualport without adding an AC_ARG_WITH([virtualport]), which means the user doesn't have an easy way to set this variable via ./configure --with-virtualport.
I think we need a v2 that adds the AC_ARG_WITH.
Ooops.

So virtualport doesn't require libnl. The rest of your logic looks okay, once we get the AC_ARG_WITH sorted out.
virtualport support requires macvtap -- at least at the moment -- which in turn requires libnl. [virtualport support could be used with directly mapped PCI devices (not needing macvtap), but there is no support for this atm. In that case the two will become independent of each other.] Will send a V2 shortly. Stefan
