From 65927b335012b2f998028c2030c412ce906425b3 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Mon, 16 Mar 2020 23:30:45 +0100 Subject: [PATCH] batman-adv: Fix rx packet/bytes stats on local ARP reply commit 36d4d68cd658d914ef73ac845705c4a89e7d9e2f upstream. The stats are generated by batadv_interface_stats and must not be stored directly in the net_device stats member variable. The batadv_priv bat_counters information is assembled when ndo_get_stats is called. The stats previously stored in net_device::stats is then overwritten. The batman-adv counters must therefore be increased when an ARP packet is answered locally via the distributed arp table.
