[dpdk-dev] [RFC] net/null: add empty promiscuous mode functions

[Ciara Power]

Adding promiscuous functions prevents sample applications failing when run
on this virtual PMD. The sample applications call promiscuous functions,
and fail if this function call returns an error, which occurs when the
virtual PMD does not support the promiscuous function being called. 

This change will be implemented for all virtual PMDs that currently do not
have existing promiscuous functions. Multicast functions will also be
added for virtual PMDs to prevent sample application breakages here also.
