The Synopsys EMAC core is configurable at device creation time, and can be configured for a different number of multicast hash bins and a different number of perfect filter entries. The device does not provide a way to query these parameters, therefore parameters are required. The Altera Cyclone V SOC has support for 256 multicast hash bins and 128 perfect filter entries, and is different than what's currently provided in the stmmac driver.
