[dpdk-users] RSS in X710 NIC

Hello all,

I am trying to operate RSS in X710 NIC.
In order to do so, I use l3fwd example.
I added a printf in l3fwd_lpm.c, right after rte_eth_rx_burst to print the lcore, queueid and nb_rx.
In my server I have 2 NICs. 82599 and X710. From each NIC I connect to a switch, and another connection to another server running pktgen, with range DST IPs.
I operate with this cmdline:
./build/l3fwd -c f -n 1 -w <PORT_PCI_ADDRESS> -- -P -p 1 -config "(0,0,1),(0,1,2)"
Where <PORT_PCI_ADDRESS> is either a port from 82599 NIC or the X710 one.

With 82599 (using ixgbe), I see packets on both queues (0,1).
With X710 (using i40e) I see packets always on queue 0.
Though there is a message that I'd expect it should work.
PMD: i40e_pf_config_rss(): Max of contiguous 2 PF queues are configured

I use DPDK 16.07. Also tried 16.11 (and had to add -parse-ptype flag).

Please advise.
