Hi,
I am trying to use the clib_socket interface to process a udp multical stream
being received by fd.io interface.
I followed the example in test_socket.c. I am registering for the stream as
follows:
s->config = "232.0.0.1:5001";
..
error = clib_socket_init (s);
..
error = clib_socket_rx (s, 100);
The packets being received are as follows:
03:16:18:555288: dpdk-input
GigabitEthernet6/0/3 rx queue 0
buffer 0x1bf26a1: current data 14, length 1428, free-list 0, clone-count 0,

I get an error on the receive. (d612a0e0).
Anyone have any ideas what could be going wrong.
Thanks,
Guy
