[RHEL5] bonding mode 0 doesn't resend IGMP after a failure [rhel-5.3.z]

accordingly. All revisions will be proofread by the Engineering Content Services team.
When a system was configured using channel bonding in "mode=0" (round-robin balancing) with multicast, IGMP traffic was transmitted via a single interface. If that interface failed (due to a port, NIC or cable failure, for example), IGMP was not transmitted via another port in the group, thus resulting in packets for the previously-registered multicast group not being routed correctly.
