Subject: [PATCH net] net: moxa: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
Date: Tue, 12 Feb 2019 23:56:00 +0800 [thread overview]
Message-ID: <1549986960-5031-1-git-send-email-albin_yang@163.com> (raw)
From: Yang Wei <yang.wei9@zte.com.cn>
dev_consume_skb_irq() should be called in moxart_tx_finished() when
skb xmit done. It makes drop profiles(dropwatch, perf) more friendly.
