Subject: net: 8139cp: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=896cebc0e261a29a6f0b20ab21d1bfc06959e91d;p=linux.git

net: 8139cp: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

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