Re: [dpdk-dev] Promiscuous Mode Feature

Small bit of context here, the described case already exists in the DTS
Dynamic Config tests.  So, would the other corner cases and "modes" justify
additional test case development, etc.

Hi all,

From my understanding, the promiscuous mode feature will verify the
functionality of promiscuous mode when it is on or off.

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

The plan for testing this feature is as follows:

Sending over a packet to verify the ports are working properly before any
testing. First to verify the promiscuous mode is enabled. With the
promiscuous being enabled, send over a packet and check if the packet

will

be received when sending it to a different destination mac address than

host/card. Then disable the promiscuous mode. The packet will only be
received if the mac address is the destination mac address. Otherwise,

the

test case will be considered a failure.

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

Please let me know if there is anything I need to add on or if there are
certain cases I need to be aware of.

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