[PATCH 5.12 443/677] RDMA/mlx5: Fix query RoCE port

From: Greg Kroah-Hartman
Date: Wed May 12 2021 - 14:57:37 EST


From: Maor Gottlieb <maorg@xxxxxxxxxx>

[ Upstream commit 7852546f524595245382a919e752468f73421451 ]

mlx5_is_roce_enabled returns the devlink RoCE init value, therefore it
should be used only when driver is loaded. Instead we just need to read
the roce_en field.

In addition, rename mlx5_is_roce_enabled to mlx5_is_roce_init_enabled.

Fixes: 7a58779edd75 ("IB/mlx5: Improve query port for representor port")
