Do I understand properly, if I set up W5100 the way above, then
socket 0 will get all the packets W5100 receives, until socket 0 RX buffer is full;
sockets 1, 2 and 3 will still get their matching data from related configured sources, with socket 0’s RX buffer receiving a copy of data (in raw format) these sockets get.
In other words, setting up MACRAW in socket 0 does not make other sockets inoperable. Please confirm.
I will check W5100 case. But it will take time.
I will feedback after test.
I have one question.
Which interface do you try to use between host and W5100? Is it SPI?
