Subject: [PATCH] net/e1000e : Fix to use dev_kfree_skb_any() instead of dev_kfree_skb()
 in _jumbo_rx_irq


Several "Warning: kfree_skb on hard IRQ" messages have been observed from
the net/e1000e driver, e1000_clean_jumbo_rx_irq() routine calling
dev_kfree_skb(). This patch fixes the above warning messages by
calling dev_kfree_skb_any() instead of dev_kfree_skb().
