[PATCH AUTOSEL for 4.15 020/124] IB/mlx5: Report inner RSS capability

From: Sasha Levin
Date: Mon Mar 19 2018 - 11:47:57 EST


From: Maor Gottlieb <maorg@xxxxxxxxxxxx>

[ 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")
