[RFC,4/5] batman-adv: ELP - adding sysfs parameter for elp interval
Commit Message
From: Linus Luessing <linus.luessing@web.de>
This parameter can be set individually on each interface and allows the
configuration of the ndp interval for the link quality measurements during
runtime. Usually it is desirable to set it to a higher (= slower) value on
interfaces which have a more static characteristic (e.g. wired interfaces)
or very dense neighbourhoods to reduce overhead.
Developed by Linus during a 6 months trainee study period in Ascom
(Switzerland) AG.
