    lwtunnel: autoload of lwt modules · 745041e2
    Robert Shearman authored
    The lwt implementations using net devices can autoload using the
    existing mechanism using IFLA_INFO_KIND. However, there's no mechanism
    that lwt modules not using net devices can use.
    
    Therefore, add the ability to autoload modules registering lwt
    operations for lwt implementations not using a net device so that
    users don't have to manually load the modules.
    
    Only users with the CAP_NET_ADMIN capability can cause modules to be
    loaded, which is ensured by rtnetlink_rcv_msg rejecting non-RTM_GETxxx
    messages for users without this capability, and by
    lwtunnel_build_state not being called in response to RTM_GETxxx
    messages.
