But it seems that this work got lost in space... openvswitch in ports is quiet old codebase without any netmap-integration and a provided patch isn't in our netmap tree: https://github.com/cnplab/ovs-netmap/blob/master/0001-datapath-Add-support-for-netmap-VALE.patch So I guess nobody uses ports/net/openvswitch these days anymore. I also found a FreeBSD kernel module was written back in 2014. But that seems also got lost, which most likely was due to ovs-netmap replacement? Thanks for any hints, -harry
