4.1.0.MCAST 4.2.4.BASE

Description (partial)

Multicast not enabled on Bundle-Ether60 on LC 1/x/cpu0. This causes complete
multicast traffic drop on bundle-ether. The trigger was bundle IP address removal during
Maintenance Window  for  link migration.

ipv4_mfwd_partner process on RP didn't send BE IM state/IP address because interface type
was not set as bundle.

This issue will not be seen every time, multicast bundle configs come from 2 paths i.e
sysdb and GSP. If it comes from GSP first then things are fine but if it comes from sysdb
then we hit this issue.
