====================
bonding: fix arp_validate desync state & race
These two patches aim to fix the possible de-sync state which the bond
can enter if we have arp_validate without arp_interval or the other way
around. They also fix a race condition between arp_validate setting and
mode changing.
Patch 01 - fixes the race condition between store_arp_validate and bond
mode change by using rtnl for sync
Patch 02 - fixes the possible de-sync state by setting/unsetting recv_probe
if arp_interval is set/unset and also if arp_validate is set/unset
v2: Fix the mode check in store_arp_validate
