+ * When the host is to be signaled, we just set a bit in a shared page
+ * and this bit will be inspected by the hypervisor within a certain
+ * window and if the bit is set, the host will be signaled. The window
+ * of time is the monitor latency - currently around 100 usecs. This
+ * mechanism improves throughput by:
+ *
+ * A) Making the host more efficient - each time it wakes up,
+ * potentially it will process morev number of packets. The
+ * monitor latency allows a batch to build up.
+ * B) By deferring the hypercall to signal, we will also minimize
+ * the interrupts.
+ *
+ * Clearly, these optimizations improve throughput at the expense of
+ * latency. Furthermore, since the channel is shared for both
+ * control and data messages, control messages currently suffer
+ * unnecessary latency adversley impacting performance and boot
+ * time. To fix this issue, permit tagging the channel as being
+ * in "low latency" mode. In this mode, we will bypass the monitor
+ * mechanism.
