hi, vpp dev


I am doing some fragment test using vpp 18.07.  IP4 Packet with offset 8 is 
dropped with trace error: 


00:20:04:661292: error-drop
  ip4-input: ip4 fragment offset == 1


I find the comment in ip4_input.h: /* Drop fragmentation offset 1 packets. */


Does someone know why? 


Because it’s a tiny fragment attack?


Cheers 
Ole
