Subject: [PATCH net-next 1/2] net/mlx5: Publish and unpublish all devlink parameters at once
Date: Tue, 14 Sep 2021 15:58:28 +0300 [thread overview]
Message-ID: <3d803cdf1104a97d23c5461869ff2f9cec12825b.1631623748.git.leonro@nvidia.com> (raw)
In-Reply-To: <cover.1631623748.git.leonro@nvidia.com>
From: Leon Romanovsky <leonro@nvidia.com>
The devlink parameters were published in two steps despite being static
and known in advance.
First step was to use devlink_params_publish() which iterated over all
known up to that point parameters and sent notification messages.
In second step, the call was devlink_param_publish() that looped over
same parameters list and sent notification for new parameters.
In order to simplify the API, move devlink_params_publish() to be called
when all parameters were already added and save the need to iterate over
parameters list again.
As a side effect, this change fixes the error unwind flow in which
parameters were not marked as unpublished.
Fixes: 82e6c96f04e1 ("net/mlx5: Register to devlink ingress VLAN filter trap")
