There seem to be a large number of places where the char pointer was

adding lots of ugly casts like this seems to contradict the whole

That does not look any better in my eyes, and there are ... what?
... hundreds of them?

Yeah it's a bit of a trade-off. There are ~140 of these, but >200 of
the removed casts. Joe also suggested we could replace these by
skb_put_u8() or so, which would be indeed be nicer. I can send a patch,
it's pretty simple.
