Subject: [PATCH net] net: nuvoton: w90p910_ether: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

From: Yang Wei <yang.wei9@....com.cn>

dev_consume_skb_irq() should be called in w90p910_ether_start_xmit()
when skb xmit done. It makes drop profiles(dropwatch, perf) more
friendly.
