The TFTP option negotiation mechanism, proposed in RFC 1782, is a
backward-compatible extension to the TFTP protocol, defined in STD 33,
RFC 1350.  It allows file transfer options to be negotiated prior to
the transfer using a mechanism which is consistent with TFTP's Request
Packet format.  The mechanism is kept simple by enforcing a request-
respond-acknowledge sequence, similar to the lock-step approach taken
by TFTP itself.  This document was written to allay concerns that the
presence of options in a TFTP Request packet might cause pathological
behavior on servers which do not support TFTP option negotiation.
