Subject: [dpdk-users] Distribution of received packets to CPU cores when using AF_XDP PMD in DPDK?
Date: Mon, 21 Jun 2021 07:40:44 +0200 [thread overview]
Message-ID: <CAAV4wTgyLdRYwp5qUTFmh5azLRWyXcsY5SgghBm5PU-K0z21Ww@mail.gmail.com> (raw)
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
