[PATCH rdma-next 2/2] IB/mlx5: Report inner RSS capability

Leon Romanovsky
2017-12-24T12:51:25Z

From: Maor Gottlieb <maorg-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Add missing inner RSS support capability as part of
the RSS supported fields.

In addition change MLX5_RX_HASH_INNER to 1UL << 31 in
order to define it as unsigned.

Fixes: 309fa3470fca ("IB/mlx5: Add support for RSS on the inner packet")
