I have make an issue for the libbpf in github, issue number 163. Andrii suggest me sending a mail here. So ,I paste out the content of the issue: Currently, libbpf do not support concurrently receive pkts using AF_XDP. For example: I create 4 af_xdp sockets on nic's ring 0. Four sockets receiving packets concurrently can't work correctly because the API of cq `xsk_ring_prod__reserve` and `xsk_ring_prod__submit` don't support concurrence. So, my question is why libbpf was designed non-concurrent mode, is the limit of kernel or other reason? I want to change the code to support concurrent receive pkts, therefore I want to find out whether this is theoretically supported. Thx.
