commit 3632c33d98f5dfddd33fc3480053911a659fcbf4 Author: Antonio Quartulli ordex@autistici.org Date: Sun Aug 26 01:05:56 2012 +0200
batman-adv: print packets re-routing on DBG_TT and ratelimit it
To simplify TranslationTable debugging it is better to print the packet rerouting message on the DBG_TT log level. In this way a developer interested in packets rerouting doesn't need to filter it out of the whole ROUTES log.
Moreover, since this message will appear for each rerouted message, it is now "ratelimited".
