From ee1377c3eef4238d89b2f99fa4d0bbbad3078b64 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 29 Aug 2006 21:18:45 -0700 Subject: [PATCH] [STRIP]: Fix neighbour table refcount leak. Found by inspection. The STRIP driver does neigh_lookup() but never releases. This driver shouldn't being doing gratuitous arp anyway. Untested, obviously, because of lack of hardware.
