From 896149ff1b2c48962b7e8eee797552c61f8d5b93 Mon Sep 17 00:00:00 2001 From: Veaceslav Falico Date: Tue, 18 Feb 2014 07:48:40 +0100 Subject: [PATCH] bonding: extend arp_validate to be able to receive unvalidated arp-only traffic Currently we can either receive any traffic as a proff of slave being up, or only *validated* arp traffic (i.e. with src/dst ip checked). Add an option to be able to specify if we want to receive non-validated arp traffic only. CC: Jay Vosburgh CC: Andy Gospodarek Signed-off-by: Veaceslav Falico Signed-off-by: David S.
