- * Module parameter 'queue_length':
- *
- * Enables queuing in the network stack when a client has run out of receive
- * descriptors. Although this feature can improve receive bandwidth by avoiding
- * packet loss, it can also result in packets sitting in the 'tx_queue' for
- * unbounded time. This is bad if those packets hold onto foreign resources.
- * For example, consider a packet that holds onto resources belonging to the
- * guest for which it is queued (e.g., packet received on vif1.0, destined for
- * vif1.1 which is not activated in the guest): in this situation the guest
- * will never be destroyed, unless vif1.1 is taken down (which flushes the
- * 'tx_queue').
- *
- * Only set this parameter to non-zero value if you know what you are doing!
