  MAC and VLAN anti-spoofing feature

  ----------------------------------

  When a malicious driver attempts to send a spoofed packet, it is dropped by

  the hardware and not transmitted.  An interrupt is sent to the PF driver

  notifying it of the spoof attempt.



  When a spoofed packet is detected the PF driver will send the following

  message to the system log (displayed by  the "dmesg" command):



  Spoof event(s) detected on VF(n)



  Where n=the VF that attempted to do the spoofing.
