reset skb->mac_header as dev_queue_xmit()\n\nIn this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is\ncalled. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which\nuse \"skb->head + skb->mac_header\", out-of-bound access occurs.\n\nThis patch replaces eth_hdr() with skb_eth_hdr() in
