Subject: net: ixp4xx_eth: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=88e425843ee26f80b82d984e8ec4b662c38eb0ed;p=android-x86%2Fkernel.git

net: ixp4xx_eth: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

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