s390/qeth: fix off-by-one in RX copybreak check
The RX copybreak is intended as the _max_ value where the frame's data should be copied. So for frame_len == copybreak, don't build an SG skb. Fixes: 4a71df50047f ("qeth: new qeth device driver") Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
