138  * Some notes about host rings:
140  * + The RX host rings are used to store those packets that the host network
145  *   mbufs in the RX host rings; the netmap port should be registered with
155  *   rings, and will be dropped as soon as the packet reaches another netmap
194 	 * (Only for physical ports, rx rings with NR_FORWARD set).
