[dpdk-users] symmetric rss for i40e

I'm modifying distributor samples so that same session goes to the same
core on i40e nic.

At first I tried, rss_key = {0x6d5a6d5a, 0x6d5a6d5a, 0x6d5a6d5a, ...},

It seems work but the rss is not distributed well and the upper 16-bit of
rss is always same as lower 16-bit.

As second try,

  struct rte_eth_hash_filter_info info;


 info.info.enable = 1;

  rte_eth_dev_filter_ctrl(port, RTE_ETH_FILTER_HASH, RTE_ETH_FILTER_SET,

but this seems nothing to do with rss.

What is the best way to get symmetric rss for distributor?

My env is dpdk-2.2.0, Ubuntu 14.04, X710-DA2.
