Subject: [PATCH net] net: amd: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
Date: Wed, 13 Feb 2019 23:14:54 +0800 [thread overview]
Message-ID: <1550070894-4602-1-git-send-email-albin_yang@163.com> (raw)
From: Yang Wei <yang.wei9@zte.com.cn>
dev_consume_skb_irq() should be called when skb xmit done. It makes
drop profiles(dropwatch, perf) more friendly.
