Subject: [PATCH net-next] net: lmc: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

From: Yang Wei <yang.wei9@....com.cn>

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

Delete a redundant comment line in lmc_interrupt().
