r8169: fix checksum broken
commit d5d3ebe3be5c5123f2d444e186717f45284151e2 upstream.
If r8196 received packets with invalid sctp/igmp(not tcp, udp) checksum, r8196 set skb->ip_summed
wit CHECKSUM_UNNECESSARY. This cause that upper protocol don't check checksum field.
I am not family with r8196 driver. I try to guess the meaning of RxProtoIP and IPFail.
RxProtoIP stands for received IPv4 packet that upper protocol is not tcp and udp.
!(opts1 & IPFail) is true means that driver correctly to check checksum in IPv4 header.
If it's right, I think we should not set ip_summed wit CHECKSUM_UNNECESSARY for my sctp packets
with invalid checksum.
If it's not right, please tell me.
