Subject: [PATCH net] net: micrel: ks8695net: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
Date: Wed, 13 Feb 2019 23:18:09 +0800 [thread overview]
Message-ID: <1550071089-4776-1-git-send-email-albin_yang@163.com> (raw)
From: Yang Wei <yang.wei9@zte.com.cn>
dev_consume_skb_irq() should be called in ks8695_tx_irq() when skb
xmit done. It makes drop profiles(dropwatch, perf) more friendly.
