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.):
