Hi Richard, 

mlx5 PMD is not compiled by default in dpdk.org versions due to OFED dependency you need to enable it compilation in configure file.
>Also in mlx5_ethdev.c -> mlx5_dev_infos_get()
>info->flow_type_rss_offloads = ~MLX5_RSS_HF_MASK; 

>was added as part of the .5 release, but the mask is undefined and fails to build.

Will check it

Hi all,

I tried switching from the Mellanox 16.11.4 release to the official DPDK LTS 16.11.5, but having issues getting it to work.

rte_eth_dev_count() returns 0, as mlx5_pci_probe() is never called from rte_eal_pci_probe_one_driver().
Anyone any idea what that would be ?  Works fine in previous Mellanox releases.

Using Centos 7.2, Ofed 4.2-1.

Also in mlx5_ethdev.c -> mlx5_dev_infos_get()
info->flow_type_rss_offloads = ~MLX5_RSS_HF_MASK; 

was added as part of the .5 release, but the mask is undefined and fails to build.
