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.
