As part of the VoW IGMP improvements, which deals with conversion of igmp packets to unicast packets, the following changes are done when the new feature is enabled: 1. IGMP/MLD packets with special addresses (addresses not part of any multicast group) will be converted to all existing clients of the AP. These packets will be directly fed to igmp multicast to unicast conversion module. 2. The IGMP/MLD packets with group specific addresses will first go to multicast enhancement module, where they will be allowed to pass and will be converted to unicast. 3. The new feature will be enabled only when multicast enhancement feature is enabled, which will be ensured at the configuration level. FR : 61063 Change-Id: I2fd5a67766c806432fbe1a12cb9654a3600100f5
