Since we stop using dev_alloc_skb on the IrDA TX frame, we constantly run into the case of the skb headroom being 0, and thus we call skb_cow for every IrDA TX frame. This patch uses a local buffer and memcpy the skb to it, saving us a kmalloc for each of those IrDA TX frames. Signed-off-by: Samuel Ortiz <samuel@sortiz.org> Signed-off-by: David S.
