  Log:
  It all started when we got some new routers, which told me the
  following when trying to upload configuration or download images
  from it: The TFTP server doesn't support the blocksize option.
  
  My curiousity was triggered, it took me some reading of RFCs and
  other documentation to find out what was possible and what could
  be done. Was plain TFTP very simple in its handshake, TFTP with
  options was kind of messy because of its backwards capability: The
  first packet returned could either be an acknowledgement of options,
  or the first data packet.
  
  Going through the source code of src/libexec/tftpd and going through
  the code of src/usr.bin/tftp showed that there was a lot of duplicate
  code, and the addition of options would only increase the amount
  of duplicate code. After all, both the client and the server can
  act as a sender and receiver.
  
  At the end, it ended up with a nearly complete rewrite of the tftp
  client and server. It has been tested against the following TFTP
  clients and servers:
  
  - Itself (yay!)
  - The standard FreeBSD tftp client and server
  - The Fedora Core 6 tftp client and server
  - Cisco router tftp client
  - Extreme Networks tftp client
  
  It supports the following RFCs:
  
  RFC1350 - THE TFTP PROTOCOL (REVISION 2)
  RFC2347 - TFTP Option Extension
  RFC2348 - TFTP Blocksize Option
  RFC2349 - TFTP Timeout Interval and Transfer Size Options
  RFC3617 - Uniform Resource Identifier (URI) Scheme and Applicability
            Statement for the Trivial File Transfer Protocol (TFTP)
  
  It supports the following unofficial TFTP Options as described at
  http://www.compuphase.com/tftp.htm:
  
  blksize2 - Block size restricted to powers of 2, excluding protocol headers
  rollover - Block counter roll-over (roll back to zero or to one)
  
  From the tftp program point of view the following things are changed:
  
  - New commands: "blocksize", "blocksize2", "rollover" and "options"
  - Development features: "debug" and "packetdrop"
  
  If you try this tftp/tftpd implementation, please let me know if
  it works (or doesn't work) and against which implementaion so I can
  get a list of confirmed working systems.
