net: b44: replace dev_kfree_skb_xxx by dev_consume_skb_xxx for drop profiles
The skb should be freed by dev_consume_skb_any() in b44_start_xmit() when bounce_skb is used. The skb is be replaced by bounce_skb, so the original skb should be consumed(not drop). dev_consume_skb_irq() should be called in b44_tx() when skb xmit done. It makes drop profiles(dropwatch, perf) more friendly. Signed-off-by: Yang Wei <yang.wei9@zte.com.cn> Signed-off-by: David S. Miller <davem@davemloft.net>
