Hi Jakub,

For this, instead of providing empty dev_ops, we suggest setting the
'eth_dev->data->promiscuous = 1' during PMD initialization.

This will show that PMD promiscuous mode enabled, and because of the how ethdev
APIs implemented, when application request to enable the promiscuous mode, it
will return success, when application request to disable the promiscuous mode it
will return error which is correct since " memif works in promisc mode only".
