            Bug ID: 1329
           Summary: Kernel BPF API changes break TAP RSS
           Product: DPDK
           Version: 23.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: [email protected]
          Reporter: [email protected]

Target Milestone: ---

The kernel BPF interface is unstable and the older format used by TAP device no longer works with current kernels. Fixing it means changing how the BPF program is loaded likely creating dependency on a version of libpbpf. Or just drop the feature.
