Hi,

A bit of context: David is going to implement a test in DTS
for promiscuous mode:

You need to check in which condition the promiscuous mode can be enabled.
Some contexts may forbid this mode. untrusted VF? flow isolation mode?

I assume you will test positive and negative in both on/off cases.

Anyone else has ideas about what to test and corner cases?
