[ovs-dev] netlink, ovs-datapath

Hello;

I am trying to do basic ovs but confused by vswitchd messages, could be
platform issue, but having hard time trying to decipher. Am running 4.15.x
kernel on gentoo, so going with latest github (openvswitch/ovs).

Can fetch sources, run "./boot.sh && make && make install", no problem.

Running ovsdb - the database path comes from other gentoo ovs installers
(v2.8.1): /var/run/openvswitch

Can anyone help enlighten me, what is the meaning of this,
"..dpif_netlink|WARN|Generic Netlink family 'ovs_datapath' does not
exist..."?.. ie I compiled packages, installed it, kernel recompile/reboot
seems fine.
