CURLOPT_TFTP_NO_OPTIONS − Do not send TFTP options requests.
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TFTP_NO_OPTIONS, long onoff);
Set onoff to 1L to exclude all TFTP options defined in RFC2347, RFC2348 and RFC2349 from read and write requests (RRQs/WRQs).
This option improves interop with some legacy servers that do not acknowledge or properly implement TFTP options. When this option is used CURLOPT_TFTP_BLKSIZE(3) is ignored.
