In the AF_PACKET fanout mode, packet reception can be load balanced among
processes. This also works in combination with mmap(2) on packet sockets.
+Currently implemented fanout policies are:
+ - PACKET_FANOUT_HASH: schedule to socket by skb's rxhash
+ - PACKET_FANOUT_LB: schedule to socket by round-robin
+ - PACKET_FANOUT_CPU: schedule to socket by CPU packet arrives on
+ - PACKET_FANOUT_RND: schedule to socket by random selection
+ - PACKET_FANOUT_ROLLOVER: if one socket is full, rollover to another
Minimal example code by David S. Miller (try things like "./test eth0 hash",
"./test eth0 lb", etc.):
