[B.A.T.M.A.N.] [PATCH] batman-adv: Fix rx packet/bytes stats on local ARP reply

[Sven Eckelmann]

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.

Fixes: 75ca71d858f5 ("batman-adv: Distributed ARP Table - add snooping functions for ARP messages")
