Subject: bonding: properly unset current_arp_slave on slave link up
From: Veaceslav Falico <[email protected]>
[ Upstream commit 5a4309746cd74734daa964acb02690c22b3c8911 ]
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.
