Hello, i am trying to use teamdriver (can't post link, google "teamdriver fedora" and it will show up), a feature that "allows multiple network interfaces to be teamed together and act like a single one". There are specific commands to test it at the previews link, but when i run teamd -f /usr/share/doc/teamd-1.8/example_configs/activebackup_ethtool_1.conf -d gives an error

Daemon process failed.
Failed: Device or resource busy

I am sure that i have configured correctly the config file, but take a look.
