[2.6 patch] do not select NET_CLS

The patch below (should apply against 2.6.15-rc2) fixes this issue.

<--  snip  -->


2.6.15-rc changes NET_CLS to being automatically select'ed when needed.

This patch confuses users since NET_CLS is a bool, and compiling an 
additional module that select's NET_CLS causes unresolved symbols since 
it's not user-visible that adding a module changes the kernel image.

This patch therefore changes NET_CLS back to the 2.6.14 status quo of 
being an user-visible option.
