Subject: net: wan: wanxl: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=73634c0851cf7cb86f7614421cf6e149520fb580;p=openwrt%2Fstaging%2Fblogic.git

net: wan: wanxl: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

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