Subject: Problems in compiling the module "/net/ieee80211"
Hi
I am trying to compile the kernel source code of .c files in
/linux-2.6.17.11/net/ieee80211 in a standalone manner. My aim is to
profile these files, especially the security functions, and to find the
bottlenecks in the implementation and then to fine tune it.
While compiling them as
gcc -D__KERNEL__ -I ../../kernel2/linux-2.6.17.11/include ieee80211_crypt.c
I initially got error with KBUILD but was able to remove it. Now
following are the errors I am getting.

can someone tell me how can i get over with these errors ? Moreover is
there any other way of profiling the specific module (/net/ieee802.11)
through which i can find out the bottleneck ???
