I was not talking about the packing functions. I was talking about the 
function which is used to trigger the handlers. It is not necessary (unless I 
miss something) to have some explicit void * casting when its parameter type 
is already void *.

I think these functions cast from char * to something like struct icmphdr * by 
first retrieving the transport header from the skb. So they do a lot more than 
your more-than-necessary-explicit casting function.

Kind regards,
