Julian Wiedmann 238965b71b net/af_iucv: build proper skbs for HiperTransport ... The HiperSockets-based transport path in af_iucv is still too closely entangled with qeth. With commit a647a02512 ("s390/qeth: speed-up L3 IQD xmit"), the relevant xmit code in qeth has begun to use skb_cow_head(). So to avoid unnecessary skb head expansions, af_iucv must learn to 1) respect dev->needed_headroom when allocating skbs, and 2) drop the header reference before cloning the skb. While at it, also stop hard-coding the LL-header creation stage and just use the appropriate helper.
