When I run the command [1] on a device that doesn't support it, I am getting:
"Successfully set following ptypes for Port 0"

I still think this is wrong and we should fix it, and introduce '-ENOTSUP' to
'rte_eth_dev_set_ptypes()' as other APIs. Since the API is experimental we can
do it later for sake of making the set for rc2.

Can we please keep tracing the discussion for this one for rc3?
