[net-next 08/15] net/mlx5e: Do not reset Receive Queue params on every type change
flat view
STALE3126d
From: Saeed Mahameed <hidden>
Date: 2018-03-28 00:43:54
Subsystem:
mellanox ethernet driver (mlx5e), mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers:

From: Tariq Toukan <redacted>
Do not implicit a call to mlx5e_init_rq_type_params() upon every
change in RQ type. It should be called only on channels creation.
Fixes: 2fc4bfb7250d ("net/mlx5e: Dynamic RQ type infrastructure")
