- * Congestion monitoring.

- * up when the congestion map is updated.
- * With explicit monitoring, an application can have more
- * fine-grained control.
- * The application installs a 64bit mask value in the socket,
- * where each bit corresponds to a group of ports.
- * When a congestion update arrives, RDS checks the set of
- * ports that are now uncongested against the list bit mask
- * installed in the socket, and if they overlap, we queue a
- * cong_notification on the socket.
- *
- * To install the congestion monitor bitmask, use RDS_CONG_MONITOR
- * with the 64bit mask.
- * Congestion updates are received via RDS_CMSG_CONG_UPDATE
- * control messages.
- *
- * The correspondence between bits and ports is
- * 1 << (portnum % 64)
