Subject: net: dscc4: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=96d26503e1deba5d12e0e4b473336479cc0965af;p=linux.git

net: dscc4: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

dev_consume_skb_irq() should be called in dscc4_tx_irq() when skb
xmit done. It makes drop profiles(dropwatch, perf) more friendly.
