The wep+tkip usage is integral to the cipher so splitting it out would 
likely slow them and, more importantly, would also require revalidation 
(there are test vectors but they're pretty limited).  These modules are 
self-contained for various reasons so I'm leary of switching.  I'll 
think about adding it under an #ifdef for those that want to save 
2Kbytes (the size of the crc tables).
