+ * \brief Option name for DGRAM socket to rate limit peers

+ * Use as the option name in \c getsockopt(3) to set the packet rate
+ * (packets per second) for peers of a datagram socket. A value of
+ * -1 means no limit set, value of 0 means to drop all packets.

+ * \note Only available for ESX (VMkernel/userworld) endpoints.

+ * An example is given below.
