Subject: Re: [PATCH v4] net/af_xdp: re-enable secondary process support

Secondary process support had been disabled for the AF_XDP PMD
because
there was no logic in place to share the AF_XDP socket file descriptors
between the processes. This commit introduces this logic using the IPC
APIs.
Rx and Tx are disabled in the secondary process due to memory mapping of
the AF_XDP rings being assigned by the kernel in the primary process only.
However other operations including retrieval of stats are permitted.

Hi Ciara,
When I tried to test the patch getting following error [1], it doesn't look
related to this patch but can you help to fix the issue, thanks.
[1]
libxdp: Couldn't find a BPF file with name xsk_def_xdp_prog.o
xsk_configure(): Failed to create xsk socket.
eth_rx_queue_setup(): Failed to configure xdp socket
Fail to configure port 2 rx queues

Hi Ferruh,
This file should be generated when libxdp is compiled.
Mine is located @ /usr/local/lib/bpf/xsk_def_xdp_prog.o
Can you check if that file is there for you? It could be in
/usr/local/lib64/bpf/ on your machine.
What kernel are you running on?
It is in: /usr/local/lib64/bpf/xsk_def_xdp_prog.o
I had to compile libxdp from source because OS package version was old
to work with af_xdp.
Is something required to point location of this file to af_xdp PMD?
I run kernel:
5.15.16-200.fc35.x86_64
