+ *
+ *            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.
