++ *
++ * 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.
