[B.A.T.M.A.N.] [PATCH] batman-adv: broadcast primary OGM on all active hard-interfaces
by Marek Lindner 04 Jul '11

04 Jul '11

The primary interface OGM has to be broadcasted on all hard-interfaces even if the primary interface is not the first interface (if_num = 0). Therefore the code has to compare the originating interface with the primary interface instead of checking the if_num.

[B.A.T.M.A.N.] [PATCH] batman-adv: pass a unique flag arg instead of a sequence of bool ones
by Antonio Quartulli 04 Jul '11

04 Jul '11

now tt_local_event() takes a flags argument instead of a sequence of boolean values which would grow up with the time.
