Hello all,
I think http://dpdk.org/dev/patchwork/patch/5389/ disabled support of indirect buffers by accident.
Am I missing something ? Is there a reason why this was disabled ?
I tested it today and it seems to work fine.
If you have no objection, could we re-enable it ?
It is a very useful feature as it enables using more descriptors than limited by the queue size.
Thanks,
- Pierre

I noticed it this week while testing my Tx indirect desc patch for
vhost side, and planned to fix it later.
So yes, please, send the fix if you have time.
Thanks,
Maxime
