Hey Kevin,
What if I have 10 ports and want all 9 ports to forward packets to port 0, this cannot done in paired.
But with this topo the user can overwrite the topo.
E.g:
- Set custom-topo 1 0
Will make those paired and those two as active only.
- set custom-topo 2 0
Will make those two as paired, but still port one will forward packets to 0.
And the active ports will be 3 ports (0,1,2)
And so on...
With this topo you can create your own topo. (Mixed between all topos or even non-pattern topo for any usage)
In my case its needed for representors and virtio.
Any traffic coming from representors/vhost (from VM) need to be forwarded from PF/phy port to the wire.
This new topo is useful for such cases.
BRs,
Wisam jaddo

Thanks for sharing the use case.
Will it be an issue that multiple cores may be sending to the same TxQ?
I didn't check to see if there is locking provided in the app.

I didn't check to see if there is locking provided in the app.
[Wisam] I've tested such case recently, and yes it will cause a seg. Fault in this solution, since multiple cores will access same queues.
I'm currently working on a fix for it, I'm planning to map single queues for each core with custom topology to avoid such scenario.

Can you use a combination of paired mode and set portlist to achieve the
same topology? or there is something you want that it doesn't cover?

Set custom topology for forwading packets by making the
given two ports as pair, in custom topology the active
ports will be the defiend in custum-topo only.
This command will be useful in testing, when special
topology is needed.
usage:
testpmd> set custom-topo (port_id_1) (port_id_2)
