+ The IMQ device(s) is used as placeholder for QoS queueing disciplines.
|

+ Every packet entering/leaving the IP stack can be directed through
|

+ the IMQ device where it's enqueued/dequeued to the attached qdisc.
|
||||
+ This allows you to treat network devices as classes and distribute
|
||||
+ bandwidth among them. Iptables is used to specify through which IMQ
|

+ device, if any, packets travel.

|

+ *
|

+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
|
||||
+ * - Correction of imq_init_devs() issue that resulted in

|

|

|

+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)

|

+ *
|

+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
|

+ * released with almost no problems. 2.6.14-x was released
|
||||
+ * with some important changes: nfcache was removed; After

|
