Some TFTP server implementations ignore the "TFTP Option extension" (RFC 1782-1784, 2347-2349), or implement it in a flawed way, causing problems with libcurl. Another switch for curl_easy_setopt "CURLOPT_TFTP_NO_OPTIONS" is introduced which prevents libcurl from sending TFTP option requests to a server, avoiding many problems caused by faulty implementations.
