+Long: tftp-no-options
+Help: Do not send any TFTP options
+Protocols: TFTP
+Added: 7.48.0
+---
+Tells curl not to send TFTP options requests.
+
+This option improves interop with some legacy servers that do not acknowledge
+or properly implement TFTP options. When this option is used --tftp-blksize is
+ignored.
