[PATCH net-next 2/2] drivers/net/oki-semi: Donot recompute IP header checksum

[roy.qing.li@gmail.com]

From: RongQing.Li <roy.qing.li@gmail.com>

If I understand correct, NETIF_F_IP_CSUM only means the hardware 
will compute the TCP/UDP checksum, IP checksum is always computed 
in software

So as a workround of hardware unable to compute small packages 
checksum, do not need to compute IP header checksum.
