I have a follow up patch that is a bit more kosher regarding the const 
handling. The challenge is that a lot of the devices have a single function 
that read/write packets with a boolean parameter for is_read. Thus, they all 
need non-const pointers and thus taint the packet. Until that is split or 
reorganised I do not think there is much point.

Good idea though :-)
