   3 Subject: batman-adv: do not add loop detection mac addresses to global tt
   4
   5 This change has been made for local TT already, add another one for
   6 global TT - but only for temporary entries (aka speedy join), to prevent
   7 inconsistencies between local and global tables in case an older
   8 batman-adv version is still announcing those entries from its local
   9 table.
