Hello.
I use this routine PA_emacExample_exampleProject. I can receive packets that match the MAC address / IP address / port number.
But I can not receive broadcast packets. Later, I know because I did not add the broadcast MAC.
I added broadcast MAC with the following piece of code:
Int32 Add_BroadcastMACAddress (Void)

return 0;

However, when receiving broadcast packets, the interrupt function does not respond。
I think that the packets has not yet triggered the interrupt.Packet is filtered out in the PA.
My purpose is very simple:
1、Normally,receiving the packets whose MAC address /IP address / port number match the MAC address/IP address/ port number stored in PA .
2、When the received packet is a broadcast packet, then it is routed directly to the host.
How can I modify the PA_emacExample_exampleProject routine to acchieve this target.
thank you！
