From 5a4309746cd74734daa964acb02690c22b3c8911 Mon Sep 17 00:00:00 2001 From: Veaceslav Falico Date: Thu, 5 Apr 2012 03:47:43 +0000 Subject: bonding: properly unset current_arp_slave on slave link up When a slave comes up, we're unsetting the current_arp_slave without removing active flags from it, which can lead to situations where we have more than one slave with active flags in active-backup mode. To avoid this situation we must remove the active flags from a slave before removing it as a current_arp_slave.
