I have two ethernet adapters in my PC.

According  devn-speedo.so  Utilites Reference I try:

#io-pkt-v4-hc -d speedo idx0:mac=XXXXXX

But it isn't work. Some error message as result.


If I try:

#io-pkt-v4-hc -d speedo mac=XXXXXX

no error messages as result, but effect is the same XXXXXX MAC address installed for both interfaces.

I need to change MAC address only first  of two etheret adapters.

Please let me correct index notation for that.
