Look into netconsole for control over Ethernet. 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
