From 45904f21655cf4f0ae7d0fab5906fe51bf56ecf4 Mon Sep 17 00:00:00 2001 From: Javier Cardona Date: Fri, 3 Dec 2010 09:20:40 +0100 Subject: nl80211/mac80211: define and allow configuring mesh element TTL The TTL in path selection information elements is different from the mesh ttl used in mesh data frames. Version 7.03 of the 11s draft calls this ttl 'Element TTL'. Signed-off-by: Johannes Berg Signed-off-by: John W.
