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"
