batman-adv: refactor batadv_tt_local_event()
Instead of passing a generic combination of flags as argument, it is easier to pass the entire tt_common structure (containing the flags already set) plus a bitfield of event flags that will be unified with the already existing ones before inserting the client in the event queue. In this way invocations of the modified function can be simplified. Signed-off-by: Antonio Quartulli <antonio@open-mesh.com> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
