From 3e25c65ed085b361cc91a8f02e028f1158c9f255 Mon Sep 17 00:00:00 2001 From: Tim Gardner Date: Thu, 29 Aug 2013 06:38:47 -0600 Subject: net: neighbour: Remove CONFIG_ARPD This config option is superfluous in that it only guards a call to neigh_app_ns(). Enabling CONFIG_ARPD by default has no change in behavior. There will now be call to __neigh_notify() for each ARP resolution, which has no impact unless there is a user space daemon waiting to receive the notification, i.e., the case for which CONFIG_ARPD was designed anyways.
