From 2186fff3675d4e774cecc8f918c05063e0367d28 Mon Sep 17 00:00:00 2001 From: Bernard Iremonger Date: Mon, 7 Mar 2016 11:40:40 +0000 Subject: [PATCH] bonding: fix crash when no slave device If a bonded device is created when there are no slave devices there is a loop in bond_ethdev_promiscuous_enable() which results in a segmentation fault. The solution is to initialise the current_primary_port to an invalid port value when the bonded port is created.
