I improved the TFTP test server to be able to do a test for this. Then I wrote up test 1238 and could repeat the problem. Then I committed a fix that made test 1238 run fine. Then I pushed the lot to git. The fix is in commit 4bea91fc: https://github.com/bagder/curl/commit/4bea91fc6773

Thanks for the report, case closed!

** [bugs:#1269] TFTP does not stop if rate is below low-speed-limit**

TFTP transfers do not timeout when data rate is below CURLOPT_LOW_SPEED_LIMIT for CURLOPT_LOW_SPEED_TIME.
Looks like Curl_speedcheck() needs to be called in tftp.c:tftp_receive_packet().
Tested by initiating a transfer with curl binary running as tftp client. Then I pulled the ethernet cable to simulate network dis-connectivity. The transfer does not timeout within the timeframe specified by CURLOPT_LOW_SPEED_TIME.
