-+ *
-+ * 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)
-+ *
-+ *             2008/08/06 - 2.6.26 - (JK)
-+ *              - Replaced tasklet with 'netif_schedule()'.
-+ *              - Cleaned up and added comments for imq_nf_queue().
-+ *
-+ *             2009/04/12
-+ *              - Add skb_save_cb/skb_restore_cb helper functions for backuping
-+ *                control buffer. This is needed because qdisc-layer on kernels
-+ *                2.6.27 and newer overwrite control buffer. (Jussi Kivilinna)
-+ *              - Add better locking for IMQ device. Hopefully this will solve
-+ *                SMP issues. (Jussi Kivilinna)
-+ *              - Port to 2.6.27
-+ *              - Port to 2.6.28
-+ *              - Port to 2.6.29 + fix rmmod not working
-+ *
-+ *             2009/04/20 - (Jussi Kivilinna)
-+ *              - Use netdevice feature flags to avoid extra packet handling
-+ *                by core networking layer and possibly increase performance.
-+ *
-+ *	       Also, many thanks to pablo Sebastian Greco for making the initial
-+ *	       patch and to those who helped the testing.
-+ *
-+ *             More info at: http://www.linuximq.net/ (Andre Correa)

-+	---help---
-+	  The IMQ device(s) is used as placeholder for QoS queueing
-+	  disciplines. Every packet entering/leaving the IP stack can be
-+	  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.
-+
-+	  More information at: http://www.linuximq.net/
-+
-+	  To compile this driver as a module, choose M here: the module
-+	  will be called imq.  If unsure, say N.
