Hi

I wonder if you please can help me with a question about the AF_XDP Poll
Mode Driver
which is integrated in DPDK.

1) How does this driver distribute received packets to the CPU Cores?
    If for example the EAL parameter -l is set to 4,5 does this mean that
received packets are
    processed by CPU cores 4 and 5 and the AF_XDP PMD distributes the
received packets
    evenly on these cores?
2) Is a round-robin principle used for selecting which core that shall
handle a received packet?
3) Is RSS (Receive Side Scaling) not used when using the AF_XDP PMD drive
in DPDK?

Thanks
Staffan
