Hello,

Is there any register or settings necessary to enable the multicast receiving i
in AM335x Ethernet module?
can we assume that unless we make settings to block the multicast receive,it will be enabled.

Regards.

    If Ethernet module is VLAN unaware mode, then you will receive all multicast packet. If you want to block multicast packets then put CPSW in vlan aware mode and add multicast address to ALE to receive multicast packets

    with regards

    Hi Mugunthan,

    What are the patches which i should add for multicast to work in ti-sdk-am335x-evm-05.05.01.00?

    I have downloaded the "git-am335x" from the git http://arago-project.org/git/projects / linux-am33x.git and i can see that these are the additional patches applied over sdk-05.05.01.00 in "drivers/net".
