ixgbe: Fix checksum error when using stacked vlan
When a skb has multiple vlans and it is CHECKSUM_PARTIAL, ixgbe_tx_csum() fails to get the network protocol and checksum related descriptor fields are not configured correctly because skb->protocol doesn't show the L3 protocol in this case. Use vlan_get_protocol() to get the proper network protocol. Signed-off-by: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp> Signed-off-by: David S. Miller <davem@davemloft.net>
