Part Number: TDA4VM

Hi, TI

We used SDK8.4 and found during the test that we could not grab the multicast text,but the broadcast was OK.
Does cpsw restrict multicast messages?
Are there any macro switches that need to be turned on in the SDK?
Which registers need to be set?

    2. if CPSW9G then are using Ethfw or Native Linux Driver or PDK app (enet_lwip_example)?

    If you want to handle any frames, you need ALE entries and policers.

    There is no MACRO related configuration to enable and disable Multicast frames.
