As this is a bit unusual stuff (ethtool -X), I guess some hints can be
useful to testers and admins :
I tested this patch on my dev machine
Broadcom Corporation NetXtreme II BCM57711E 10Gigabit PCIe
(Hewlett-Packard Company NC532i Dual Port 10GbE Multifunction BL-C
Adapter)
# ethtool -X eth1 weight 0 1 0 2 0 4 0 8 0 16 0 32
# ethtool -x eth1
RX flow hash indirection table for eth1 with 16 RX ring(s):
0: 1 1 3 3 3 3 5 5
8: 5 5 5 5 5 5 7 7
16: 7 7 7 7 7 7 7 7
24: 7 7 7 7 7 7 9 9
32: 9 9 9 9 9 9 9 9
40: 9 9 9 9 9 9 9 9
48: 9 9 9 9 9 9 9 9
56: 9 9 9 9 9 9 11 11
64: 11 11 11 11 11 11 11 11
72: 11 11 11 11 11 11 11 11
80: 11 11 11 11 11 11 11 11
88: 11 11 11 11 11 11 11 11
96: 11 11 11 11 11 11 11 11
104: 11 11 11 11 11 11 11 11
112: 11 11 11 11 11 11 11 11
120: 11 11 11 11 11 11 11 11
After some (distributed) trafic on eth1 I get :
[root@svivoipvnx021 ~]# ethtool -S eth1|grep rx_ucast_packets
[0]: rx_ucast_packets: 62
[1]: rx_ucast_packets: 15870
[2]: rx_ucast_packets: 9
[3]: rx_ucast_packets: 31507
[4]: rx_ucast_packets: 0
[5]: rx_ucast_packets: 63106
[6]: rx_ucast_packets: 0
[7]: rx_ucast_packets: 122051
[8]: rx_ucast_packets: 1
[9]: rx_ucast_packets: 248071
[10]: rx_ucast_packets: 0
