Hi, 17.11.10 contains: [1] 4cd784b0 "net/mlx5: fix Rx CQ doorbell synchronization on aarch64" Which is a backport from 94a24aaf
But if you build on arm64 with MLX5 enabled that breaks like: mlx5_rxtx_vec_neon.h:1035: undefined reference to `rte_cio_wmb' I found and confirmed that adding the following on top of 17.11.10 fixes the issue [2] 52bd60a5 "eal/arm64: define coherent I/O memory barriers" [1]: https://git.dpdk.org/dpdk-stable/commit/?id=4cd784b02d29f706ff2297b6f65eeb680c0af9ff [2]: https://git.dpdk.org/dpdk/commit/?id=52bd60a5 -- Christian Ehrhardt Staff Engineer, Ubuntu Server Canonical Ltd
