i neeed to allocate an skbuff in my function at user level & to mess with it . Is it possible to do that .can u specify which function to use(i tried with the alloc_skb( ) but i m failing with all those header errors related to skbuff.h & so on all related things)

assume if i change the contents of some header files . Do i need to recompile the kernel to see the changes

Please help me out of this.
