Actually there is. Before this update, bond interfaces (specifically 802.3ad) were defaulting to ARP enabled. After the upgrade, they are created with NOARP set on the link.
pre-upgrade:
eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP>
post-upgrade: eth0: <BROADCAST,MULTICAST,NOARP,SLAVE,UP,LOWER_UP> eth1: <BROADCAST,MULTICAST,NOARP,SLAVE,UP,LOWER_UP> bond0: <BROADCAST,MULTICAST,NOARP,MASTER,UP,LOWER_UP>
