Subject: [PATCH net] net: fsl_ucc_hdlc: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
Date: Wed, 6 Feb 2019 00:14:51 +0800 [thread overview]
Message-ID: <1549383291-5511-1-git-send-email-albin_yang@163.com> (raw)
From: Yang Wei <yang.wei9@zte.com.cn>
dev_consume_skb_irq() should be called in hdlc_tx_done() when skb
xmit done. It makes drop profiles(dropwatch, perf) more friendly.
