-+ *
-+ * Authors: Patrick McHardy, <kaber@trash.net>
-+ *
-+ * 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.
-+ *
-+ *
-+ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
-+ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
-+ * recursive locking. New initialization routines to fix 'rmmod' not
-+ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
-+ *
-+ * Also, many thanks to pablo Sebastian Greco for making the initial
-+ * patch and to those who helped the testing.
-+ *
