NDK Broadcast and Multicast rate limits port0 (host port)

I'm trying to enable rate limiting for broadcast and multicast packets. I would like broadcast/multicast packets to be freely forwarded between port1 and port2. However, I want to limit the number of broadcasts/multicast packets received on port0 (host port). I have tried the following code with no success:

// Prescaler set to occur every 1ms

CPSWALEPrescaleSet(SOC_CPSW_ALE_REGS, 125000000 / 1000);

CPSWALEBroadcastRateLimitSet(SOC_CPSW_ALE_REGS, 0, 1); // 1 broadcasts per millisecond
CPSWALEMulticastRateLimitSet(SOC_CPSW_ALE_REGS, 0, 1); // 1 multicasts per millisecond
CPSWALERateLimitRXMode(SOC_CPSW_ALE_REGS);
CPSWALERateLimitEnable(SOC_CPSW_ALE_REGS);

I would appreciate any help. I'm developing with an AM335x and am using industrial sdk V1.1.0.3.
