Subject[PATCH AUTOSEL for 4.15 020/124] IB/mlx5: Report inner RSS capability
Date
From: Maor Gottlieb <maorg@mellanox.com>

[ Upstream commit 4e2b53a5cb5a8243284dd7ec4980d2dc556e79f0 ]

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")
