Subject: [PATCH net-next V6 05/13] devlink: pass struct devlink_port * as arg to devlink_nl_param_fill()
Date: Tue,  8 Jul 2025 20:04:47 -0700	[thread overview]
Message-ID: <20250709030456.1290841-6-saeed@kernel.org> (raw)
In-Reply-To: <20250709030456.1290841-1-saeed@kernel.org>

From: Jiri Pirko <jiri@nvidia.com>

As the follow-up patch will need to get struct devlink_port *, avoid
unnecessary lookup and instead of port_index pass the struct
devlink_port * directly.
