From 95d392784dd0a51e4216e075f04a68c922745985 Mon Sep 17 00:00:00 2001 From: Antonio Quartulli Date: Sat, 16 Jan 2016 16:40:15 +0800 Subject: batman-adv: keep track of when unicast packets are sent To enable ELP to send probing packets over wireless links only if needed, batman-adv must keep track of the last time it sent a unicast packet towards every neighbour. For this purpose a 2 main changes are introduced: 1) a new member of the elp_neigh_node structure stores the last time a unicast packet was sent towards this neighbour; 2) a wrapper function for sending unicast packets is implemented. This function will simply update the member describe din point 1) and then forward the packet to the real sending routine. Point 2) implies that any code-path leading to a unicast sending now has to use the new wrapper.
