From 380ab7e3d59d790e05d39f3c1d4a6039ef0e3901 Mon Sep 17 00:00:00 2001 From: Yang Wei <yang.wei9@zte.com.cn> Date: Wed, 13 Feb 2019 23:19:14 +0800 Subject: [PATCH] net: natsemi: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles dev_consume_skb_irq() should be called when skb xmit done. It makes drop profiles(dropwatch, perf) more friendly. Signed-off-by: Yang Wei <yang.wei9@zte.com.cn> Signed-off-by: David S.
