[OVS] mcast-snooping: Flush ports mdb when VLAN configuration changed.
Last modified: 2017-10-06 14:18:00 EDT
+++ This bug was initially created as a clone of Bug #1456358 +++ This bugzilla is opened in order to make include the following upstream fix[1] in downstream OVS 2.6. Description (from github): If VLAN configuration(e.g. id, mode) change occurs, the IGMP snooping-learned multicast groups from this port on the VLAN are deleted. This avoids a MCAST_ENTRY_DEFAULT_IDLE_TIME delay before mdb is updated again. Hardware switches (e.g. cisco) also do that.
