Hi
look at PF_RING/drivers/DNA/igb-3.1.16-DNA/src/igb_dna.c
void dna_check_enable_adapter(struct igb_adapter *adapter) {
adapter->dna.dna_enabled = 0; /* Default */
if(strcmp(adapter->netdev->name, "eth0") == 0)
return; /*
We never enable DNA on eth0 as this might be
the management interface
*/
Please use another interface other than eth0 that we assume is used for
management and not for DNA.

"Debugging is twice as hard as writing the code in the first place. Therefore,
if you write the code as cleverly as possible, you are, by definition, not
smart enough to debug it. - Brian W. Kernighan
