I haven't used it personally, but it's supported in U-boot. What kind of UDP or TCP packets do you want to send? Many of the common UDP-based protocols have some support (NFS, TFTP and some others), but keep in mind that U-boot is not a multitasking environment and so there is no concept of 'servers'. Apart from netconsole, all network communications must start from the target. regards, Ben
