12 + * Authors: Patrick McHardy, <kaber@trash.net>
14 + * The first version was written by Martin Devera, <devik@cdi.cz>
16 + * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
17 + * - Update patch to 2.4.21
18 + * Sebastian Strollo <sstrollo@nortelnetworks.com>
19 + * - Fix "Dead-loop on netdevice imq"-issue
20 + * Marcel Sebek <sebek64@post.cz>
21 + * - Update to 2.6.2-rc1
23 + * After some time of inactivity there is a group taking care
24 + * of IMQ again: http://www.linuximq.net
27 + * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including
28 + * the following changes:
30 + * - Correction of ipv6 support "+"s issue (Hasso Tepper)
31 + * - Correction of imq_init_devs() issue that resulted in
32 + * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
33 + * - Addition of functionality to choose number of IMQ devices
34 + * during kernel config (Andre Correa)
35 + * - Addition of functionality to choose how IMQ hooks on
36 + * PRE and POSTROUTING (after or before NAT) (Andre Correa)
37 + * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
40 + * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
41 + * released with almost no problems. 2.6.14-x was released
42 + * with some important changes: nfcache was removed; After
43 + * some weeks of trouble we figured out that some IMQ fields
44 + * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
45 + * These functions are correctly patched by this new patch version.
47 + * Thanks for all who helped to figure out all the problems with
48 + * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
49 + * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
50 + * I didn't forget anybody). I apologize again for my lack of time.
