created new q_disc, inserted module, tc tells me unknown qdisc

["George P Nychis" <gnychis@xxxxxxx>]

Hi,

I am trying to install a proprietary qdisc made for research, it is not publically released yet, however its been used several times so i know it works.

The files included are:
q_xcp.c:
   static int xcp_parse_opt()
   static int xcp_print_opt()
   static int xcp_print_xstats()
   struct qdisc_util xcp_util = { "NULL", "xcp" ..... };

sch_xcp.c:
   static int xcp_enqueue()
   static int xcp_requeue()
   static struct sk_buff * xcp_dequeue()
   ....
   ....
   struct Qdisc_ops xcp_qdisc_ops ={ NULL,NULL,"xcp",.... };

   printk(KERN_INFO "XCP qdisc module loaded.\n");
   return register_qdisc(&xcp_qdisc_ops);


So, i make everything successfully, it creates q_xcp.so and copies it to /usr/lib and sch_xcp.o which it copies to /lib/modules/... so then I "insmod sch_xcp" and i see in dmesg:
"XCP qdisc module loaded."

I then try:
"tc qdisc add dev eth0 root xcp capacity 10Mbit limit 500" and get:
"Unknown qdisc "xcp", hence option "capacity" is unparsable"

So then I read the INSTALL further to find some sort of solution and it mentions:
This again assumes "tc" version is 2.4.7.  If your "tc" is a different
version, download the iproute2 source code, and edit Makefile to
point "TC_INCLUDE" to "-I..../iproute2/include -I..../iproute2/tc"

So, i did that, and i recompiled the q_xcp.so:
lanthanum-ini src-1.0.1 # make q_xcp.so
cc -O2 -fPIC -I/var/tmp/portage/iproute2-2.6.11.20050310-r1/work/iproute2-2.6.11/include/ -I/var/tmp/portage/iproute2-2.6.11.20050310-r1/work/iproute2-2.6.11/tc_include -o q_xcp.o -c q_xcp.c
ld -shared -o q_xcp.so q_xcp.o
rm -f q_xcp.o

But i still get the same error.... so then my very final last effort was to move q_xcp.c to my iproute2 source code tc/ directory and added this to the makefile:
TCMODULES += q_xcp.o

Then I compiled tc, and i check tc to see if the xcp qdisc functions were loaded:
lanthanum-ini tc # nm tc | grep xcp
080531ec t xcp_parse_opt
080533e0 t xcp_print_opt
08053426 t xcp_print_xstats
08070cc0 D xcp_util

And finally:
lanthanum-ini tc # ./tc qdisc add dev ath0 root xcp capacity 54Mbit limit 500
Unknown qdisc "xcp", hence option "capacity" is unparsable


I have no clue :(  I figured that putting the .so into /usr/lib would have been enough.  Sorry for the long e-mail, I hope someone can help, and thank you for your time even if you don't know the solution but read this :)
