Hi Jeff,
Understood and that makes sense.
Thanks for the reply.
Would it be possible to generalize your use case for NULL, as need for
adding special marker pointers in order to either get cache alignment or
signal the ring consumer (e.g. null object implies end of transmission)?
I think that ch

Hi,
So if I have multiple queues and was using ETH_MQ_RX_NONE (and therefore
utilizing RSS), it will stop working for me now after this patch ?

Hi Pepe,
I?m assuming you?re creating and accessing the ring safely (i.e.,
single/multiple consumers and producers).
Based on the code, these return values are possible if the ring somehow got a
NULL object pointer enqueued to it.

Yes, you should use ETH_MQ_RX_RSS to explicitly enable RSS.

I was using NULLs in the ring to cache-line pad and maintain alignment
during burst dequeue. The receiving code discards the NULLs as NOPs.

Hi,
I am able to load the igb_uio driver and run my application on dpdk with RSS
all fine. But when I try to enable flow director mask, I get an error. When I
dig into the code, noticed that igb driver does not support flow director,
however ixgbe driver supports. Since we have loaded igb drive
