Commit Message

Linus Lüssing July 2, 2010, 12:10 a.m. UTC
This commit introduces the -t switch for originator table output. It
makes use of the new last-seen field in batman-adv, the user can specify
a timeout interval in seconds (with 3 digits precision before and after
a possible dot) if he/she considers a node as dead after this time.
(of course this is just influencing the displaying and not actually
declearing a node as dead for routing decisions)
