Hi All, I am using linux-2.6.31 kernel and a slightly modified version of mcp251x driver. If I set the socket options using CAN_RAW_RECV_OWN_MSGS, to receive the sent frames, it is not receiving back.
I enabled local echo (IFF_ECHO), in my code. I don't know why it is not working. I believe that it is being taken care by the low level CAN subsystem. I saw that when setsockopt(CAN_RAW_RECV_OWN_MSGS) is called, recv_own_msgs member of raw_sock is updated. But, is there any way to get this information in my driver. So, that I can support the local loopback. Please do the needful. Thanks & Regards, Navaneethan P
