Currently, driver overrides the value of multicast_filter_bins based on the hash table size. If the feature is not supported, hash table size reads 0 however the value of multicast_filter_bins remains set to default HASH_TABLE_SIZE which is incorrect. Let's extend the use of the property snps,multicast-filter-bins to xgmac so it can be set to 0 via devicetree to indicate multicast filtering is not supported.
