Raw Ethernet without TCP/IP

Former Member

I have an application that requires that I be able to send and recieve raw ethernet packets.  I want to do this using the ARM and embedded mac since it is there already.  Does anybody have a pointer for how to accomplish this in software on the Zynq.  I have been looking at the documentation for the 'lightweight ip' library but I have not been able to parse how to interact with the ethernet to achieve what I want.

Thanks

    I'm looking at doing the same thing. I've been looking at lwIP also, but as I was looking online, I ran across this in the wiki:

    "Do not confuse the LwIP raw API with raw ethernet or ip sockets. The former is a way of interfacing the lwip network stack (including tcp and udp), the later refers to processing raw ethernet or ip data instead of tcp connections or udp packets."

    If you're trying to send/receive raw ethernet packets, lwip is not something you need to use. Have you found anything useful yet?

    Raw sockets on Linux is mature and well documented. Google for SOCK_RAW, raw sockets. You can develop on your desktop top, and then cross-compile for your target system. Linux is cool that way.

    You'll likely also want WireShark, libpcap, tcpdump. Google them; see if they can help you do what you're trying to do.

    A backgrounder on Berkeley sockets and more usual network programming will likely also be useful.
