[dpdk-dev] Promiscuous Mode Feature

[dpdk-dev] Promiscuous Mode Feature

[David Liu]

Hi all,

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

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.

Thanks,

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?

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.

But there is no way other than some logs to indicate these.
Maybe we should add some state in port info to indicate this?

 From what I know, I not sure if that is possible to add these states into
the test case?
 But let me know what you think.
