From: Nicolas Dichtel <nicolas.dichtel@xxxxxxxxx>
commit 41009481b690493c169ce85f591b9d32c6fd9422 upstream.
The function geneve_dev_create_fb() (only used by ovs) never calls
rtnl_configure_link(). The consequence is that dev->rtnl_link_state is
never set to RTNL_LINK_INITIALIZED.
During the deletion phase, the function rollback_registered_many() sends
a RTM_DELLINK only if dev->rtnl_link_state is set to RTNL_LINK_INITIALIZED.
Fixes: e305ac6cf5a1 ("geneve: Add support to collect tunnel metadata.")
