  * To Fix:
  *             IP fragmentation wants rewriting cleanly. The RFC815 algorithm is much more efficient
  *             and could be made very efficient with the addition of some virtual memory hacks to permit
  *             the allocation of a buffer that can then be 'grown' by twiddling page tables.

+ *             Output fragmentation wants updating along with the buffer management to use a single
  *             interleaved copy algorithm so that fragmenting has a one copy overhead. Actual packet
  *             output should probably do its own fragmentation at the UDP/RAW layer. TCP shouldn't cause
  *             fragmentation anyway.
