Subject: [PATCH 4.18 053/135] net/mlx5: Check for SQ and not RQ state when modifying hairpin SQ
4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alaa Hleihel <alaa@...lanox.com>
[ Upstream commit 6b359d5550a1ae7a1269c9dc1dd73dfdc4d6fe58 ]
When modifying hairpin SQ, instead of checking if the next state equals
to MLX5_SQC_STATE_RDY, we compare it against the MLX5_RQC_STATE_RDY enum
value.
The code worked since both of MLX5_RQC_STATE_RDY and MLX5_SQC_STATE_RDY
have the same value today.
This patch fixes this issue.
Fixes: 18e568c390c6 ("net/mlx5: Hairpin pair core object setup")
