I got very big packet size (more than mtu) in attack log? This issue will be related with offload features of NIC. For INtel 82599 I recommend disable all offload:
```bash
ethtool -K eth0 gro off gso off tso off
```
How I can enable hardware filtration for Intel 82599 NIC? Install patched ixgbe driver from PF_RING distro and apply this patch to Makefile and recompile tool:
```bash
fastnetmon.o: fastnetmon.cpp
