@Robert Cotter Thank you for your reply ！

I try the solution you given , but i didn’t work.

Maybe it’s the pf\_ring that causes the problem.  
When i used tcpdump, i finded the same problem of Dropped Packets.  
Runtime environment:

NIC is Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe  
pf\_ring version is 7.1.0  
bro 2.5.5  
linux:centos
