Hi,

sorry to be late to reply.

I changed the code which insert src and dst as you teach me, but It didn't
work well.

And then, I have a question that RSS verification value from 82599
Datasheet is really right. I do an experiment. I set two
machines({IPv4(161, 142, 100, 80), IPv4(66, 9, 149, 187),
1766, 2794, 0x323e8fc2, 0x51ccc178}), and I make receiver machine use
Native Linux(3.16.4) and ixgbe(3.22.3). Also I insert printk in ixgbe which
print skb->hash value.

I checked the skb->hash value in dmesg. However, It didn't match with the
value from 82599 Datasheet 7.1.2.8.3 RSS Verification Suite.

Please let me know if you have any insights.
