Subject: [PATCH net 5/5] net/mlx5e: Fix potentially misleading debug message
Date: Sun, 9 Nov 2025 11:37:53 +0200 [thread overview]
Message-ID: <1762681073-1084058-6-git-send-email-tariqt@nvidia.com> (raw)
In-Reply-To: <1762681073-1084058-1-git-send-email-tariqt@nvidia.com>
From: Gal Pressman <gal@nvidia.com>
Change the debug message to print the correct units instead of always
assuming Gbps, as the value can be in either 100 Mbps or 1 Gbps units.
Fixes: 5da8bc3effb6 ("net/mlx5e: DCBNL, Add debug messages log")
