I'm actually not worried so much about these packets since these

drivers should be converted to skb frags as otherwise they'll

probably stop working after a while due to memory fragmentation.
But yeah for correctness we definitely should address this in

skb_splice_bits.
I still think Jarek's approach (the copying one) is probably the

easiest for now until we can find a better way.
