Hmm. I wonder if the reason might be that the skb itself is long enough,
but has so much tailroom that it doesn't have enough headroom, but when
we reallocate it to have more headroom we actually later don't use the
extra tailroom. That would explain why I don't get truesize bugs
although I do get a warning (from the modified pskb_expand_head()) that
I mustn't reallocate the buffer.
