So maybe you could enlighten me. I have an AM335x board which uses the integrated CPSW switch. This switch is supported by the current Linux tree [2]. Currently, the driver only uses the switch port where the frames are came in and go out only internally. My question is: is there already a common way to exchange the information on which port a frame came in (recvfrom) and should go out (sendto) with a userspace application which I could adapt for the CPSW driver? For outgoing frames I'm using raw sockets, but for incoming frames UDP is needed, so it should be possible to keep the information through the TCP/IP stack. Thanks for your hints and help!
