/*
 * From RFC 1831:
 *
 * "A record is composed of one or more record fragments.  A record
 *  fragment is a four-byte header followed by 0 to (2**31) - 1 bytes of
 *  fragment data.  The bytes encode an unsigned binary number; as with
 *  XDR integers, the byte order is from highest to lowest.  The number
 *  encodes two values -- a boolean which indicates whether the fragment
 *  is the last fragment of the record (bit value 1 implies the fragment
 *  is the last fragment) and a 31-bit unsigned binary value which is the
 *  length in bytes of the fragment's data.  The boolean value is the
 *  highest-order bit of the header; the length is the 31 low-order bits.
 *  (Note that this record specification is NOT in XDR standard form!)"
 *
 * The Linux RPC client always sends its requests in a single record
 * fragment, limiting the maximum payload size for stream transports to
 * 2GB.
