sent multicaste messages every 1ms

Hi,

I eventually success porting dual port ethernet a week ago.

Becuase you guys helped me a lot like above.

If anyone need my help to use dual port gbe, I can help you.

But, I met another problem when I test the network founction.

That is when I sent multicaste messages every 1ms, It becomes back out. i mean die.

But every 100ms is OK with my borad.

Our spec of this :

1. get multicast messages every 1ms from linux server (40Byte)

2. assemble the data around 126Byte and send back to linux server.

I don't know what do I have to do now. Just I am doing changing all of variable which I think concerned with this problem.

But as I mentioned it doesn't work.

Please help me.

Thanks, Ryan. 1

    I make progress here a little bit.

    Actually  it's not a progress, :) just I check one thing more.

    That is just eth0 works fine but eth1 doesn't work with 1ms multicast receive but it works with 100ms muticast recevie.

    Just I think It doesn't work with accumulator when it set up in Setup_Rx in numu_eth.c.

    Anybody have any ideas? Please tell me someone who have any idea about this.

    Thanks, Ryan

    Hi ryan,
    Can you share your project that supports multicast on both the ports. we look forward to your help in solving our problem. Also suggest what are the files that need to be modified for this?
