Subject: [patch net-next v2 13/15] devlink: move port_fn_state_get/set() to devlink_port_ops
Date: Fri, 26 May 2023 12:28:39 +0200	[thread overview]
Message-ID: <20230526102841.2226553-14-jiri@resnulli.us> (raw)
In-Reply-To: <20230526102841.2226553-1-jiri@resnulli.us>

From: Jiri Pirko <jiri@nvidia.com>

Move port_fn_state_get/set() from devlink_ops into newly introduced
devlink_port_ops.

Signed-off-by: Jiri Pirko <jiri@nvidia.com>

v1->v2:
- avoid ops check as they no longer could be null
