   * `strict`: Enable strict mode. MySQL warnings are treated as errors.
   * `timeout`: **Driver** side connection timeout. The value must be a string of decimal numbers, each with optional fraction and a unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. To set a server side timeout, use the parameter [`wait_timeout`](http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_wait_timeout).

-### TLS support
-For TLS support set the `tls` parameter to one of the following values:
-
- * `true`: Server certificate is signed by a trusted authority.
- * `skip-verify`: Server certificate is self-signed with no root authority.
- * `custom`: Server certifiate is signed by a self-managed authority, and/or a client certificate is used. `custom` can be any value that coorisponds to a custom `tls.Config` registered with [`mysql.RegisterTLSConfig`](http://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).

 ### `LOAD DATA LOCAL INFILE` support
 For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
