    ovs/vxlan: fix rtnl notifications on iface deletion · cf5da330
    Nicolas Dichtel authored
    The function vxlan_dev_create() (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.
    
    Note that the function vxlan_dev_create() is moved after the rtnl stuff so
    that vxlan_dellink() can be called in this function.
    
    Fixes: dcc38c03 ("openvswitch: Re-add CONFIG_OPENVSWITCH_VXLAN")
