From: Alin Năstac Date: Tue, 24 May 2016 15:02:20 +0000 (+0200) Subject: netifd: Add option to configure gc_stale_time for each device X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=fef10041f3a495d79f03f99bdf416a68a0ee91aa;p=oweals%2Fnetifd.git netifd: Add option to configure gc_stale_time for each device The UCI parameter neighgcstaletime allows to control how much time will STALE entries be kept in the neighbour table for both IPv4 and IPv6.
