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, ...},
rss_key_len=52.
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_type = RTE_ETH_HASH_FILTER_SYM_HASH_ENA_PER_PORT;
info.info.enable = 1;
rte_eth_dev_filter_ctrl(port, RTE_ETH_FILTER_HASH, RTE_ETH_FILTER_SET,
&info);
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.
