Date: Fri, 10 Dec 2010 16:59:50 +0200 From: Octavian Purdila <opurdila@...acom.com> To: netdev@...r.kernel.org Cc: Lucian Adrian Grijincu <lucian.grijincu@...il.com>, Vlad Dogaru <ddvlad@...edu.org>, Octavian Purdila <opurdila@...acom.com> Subject: [PATCH] iproute2: initialize the ll_map only once Avoid initializing the LL map (which involves a costly RTNL dump) multiple times.
