[PATCH 4.15 020/168] IB/mlx5: Report inner RSS capability
From: Greg Kroah-Hartman
Date: Tue Apr 10 2018 - 18:26:43 EST
4.15-stable review patch. If anyone has any objections, please let me know.
------------------
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")
