Hi,

I'm almost sure 82599ES doesn't support RSS with the L4 protocols (TCP,
UDP, etc). As far as I remember I hit this issue about a year ago.

What is the value of `dev_info.flow_type_rss_offloads` obtained like:

rte_eth_dev_info dev_info;
rte_eth_dev_info_get(nic_port_id, &dev_info);


The `flow_type_rss_offloads` contains the supported RSS flags by the device.
