The MDB maintained by the bridge is limited. When the bridge is configured for IGMP / MLD snooping, a buggy or malicious client can easily exhaust its capacity. In SW datapath, the capacity is configurable through the IFLA_BR_MCAST_HASH_MAX parameter, but ultimately is finite. Obviously a similar limit exists in the HW datapath for purposes of offloading. In order to prevent the issue of unilateral exhaustion of MDB resources, introduce two parameters in each of two contexts: [...]
