    Here it is again - slightly modified & smaller:
      - update to 2009-06 (Pieter's patch was for U-Boot 1.2.0)
      - README.dns is added
      - syntax is changed (now takes a third option, the env var to store
        the result in)
      - add a random port() function in net.c
      - sort Makefile in ./net/Makefile
      - dns just returns unless a env var is given
      - run through checkpatch, and clean up style issues
      - remove packet from stack
      - cleaned up some comments
      - failure returns much faster (if server responds, don't wait for
      - use built in functions (memcpy) rather than byte copy.
