+ *
+ * The first version was written by Martin Devera, <devik@cdi.cz>
+ *
+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
+ * - Update patch to 2.4.21
+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
+ * - Fix "Dead-loop on netdevice imq"-issue
+ * Marcel Sebek <sebek64@post.cz>
+ * - Update to 2.6.2-rc1
+ *
+ * After some time of inactivity there is a group taking care
+ * of IMQ again: http://www.linuximq.net
+ *
+ *
+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including
+ * the following changes:
+ *
+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
+ * - Correction of imq_init_devs() issue that resulted in
+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
+ * - Addition of functionality to choose number of IMQ devices
+ * during kernel config (Andre Correa)
+ * - Addition of functionality to choose how IMQ hooks on
+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
+ * - Cosmetic corrections (Norbert Buchmuller) (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
+ * some weeks of trouble we figured out that some IMQ fields
+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
+ * These functions are correctly patched by this new patch version.
+ *
+ * Thanks for all who helped to figure out all the problems with
+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
+ * I didn't forget anybody). I apologize again for my lack of time.

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

+ 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.
