Description:
http://dev.mysql.com/doc/relnotes/mysql-cluster/7.4/en/mysql-cluster-news-7-4-11.html

----
For busy servers, client connection or communication failure could occur if an I/O-related system call was interrupted. The mysql_options() C API function now
has a MYSQL_OPT_RETRY_COUNT option to control the number of retries for interrupted system calls. (Bug #22336527)

How to repeat:
I don't see it documented anywhere except in the change history.

Suggested fix:
Put a note in 
http://dev.mysql.com/doc/refman/5.7/en/mysql-options.html
mentioning 7.4.11+, 7.5.1+ have this option?

5.8.0 got it too, but can't document unreleased version....

Wrong category. This is C API, not Cluster.

Note that in MySQL 5.6 and 5.7 (unlike in 8.0), MYSQL_OPT_RETRY_COUNT is available only for Cluster, as of 7.4.11 (for 5.6) and 7.5.1 (for 5.7).
