RAW socket and CONFIG_FILTER

Hi,
Im doin a project on DHCp client-server setup. i have to use RAW sockets in the code for this. The call PF_PACKET, SOCK_RAW as the first two arguments. The code compiles but when i try to start the Dhcp client, I get an error saying "Make sure CONFIG_PACKET and CONFIG_FILTER is enabled". I tried to build the kernel using a source tree. I found CONFIG_PACKET=y but didnt find CONFIG_FILTER. So i added a line CONFIG_FILTER=y. I got the foll error
Heres a full snapshot of the error :
bash-3.1# make
HOSTLD scripts/kconfig/conf
scripts/kconfig/conf -s arch/i386/Kconfig
.config:384:warning: trying to assign nonexistent symbol FILTER
#
# configuration written to .config
#
CHK include/linux/version.h
UPD include/linux/version.h
CHK include/linux/utsrelease.h
UPD include/linux/utsrelease.h
SYMLINK include/asm -> include/asm-i386
ln: creating symbolic link `include/asm' to `asm-i386': Operation not permitted
make: *** [include/asm] Error 1
bash-3.1#
How else can i add it? Is there ne other way out. Im using Fedora 6 with 2.6.20 source tree.

Pls help
Thanks in advance

raw2gif

raw2gif(1)						      General Commands Manual							raw2gif(1)

NAME

       raw2gif	-  A  program to convert RAW image data into GIF files.  Only one image can be handled.  The RAW image file is assumed to hold one
       pixel color in one byte, and therefore the file size must be Width times Height as specified by the -s option below.

USAGE

       raw2gif [-q] -s Width Height [-p ColorMapFile] [-h] RawFile

       If no RawFile is given, Raw2Gif will try to read RAW data from stdin.  The generated GIF File is dumped to stdout.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

	       Quiet mode.  Defaults off on MSDOS, on under UNIX.  Controls printout of running scan lines. Use -q- to invert.

       -s Width Height

	       the dimensions of the image MUST be specified in the command line.  The RAW image file size must  be  exactly  Width  times  Height
	      bytes (each byte is one pixel color).

       [-p ColorMapFile]

	       Color  map  to  load  for  given RAW image.  This file has 4 integers in line (ColorIndex Red Green Blue), and the ColorIndex is in
	      order starting from 1. See GifClrMp, which can also use/create these bitmap files. If no color map is specified,	uses  the  EGA	16
	      color pallete as default color map.

       [-h]

	       Print one line of command line help, similar to Usage above.
