Description:
The TCP KeepAlive setting is specified in milliseconds!! NOT in seconds as this manual incorrectly states.

I just double checked using Wireshark.

How to repeat:
1) On the MySQL server: start wireshark and have it capturing for port 3306.
2) On a client (different PC) start a test app that connects to MySQL with KeepAlive set to 60, 
3) Observe a flood of Keepalive packets in Wireshark.

Suggested fix:
Change documentation.

Note: As per MySQL Bug #69484, Connector/Net was updated to behave as the documentation states, which is to treat the value as seconds.
