Subject: net: apple: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5f5a8c75daed965a3631ab98a783846260d2729d;p=linux.git

net: apple: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

dev_consume_skb_irq() should be called in mace_interrupt() when skb
xmit done. It makes drop profiles(dropwatch, perf) more friendly.
