Subject: [PATCH net 1/4] net/mlx5: fs, Fix inverted cap check in tx flow table root disconnect
Date: Tue, 20 Jan 2026 10:16:51 +0200 [thread overview]
Message-ID: <20260120081654.1639138-2-tariqt@nvidia.com> (raw)
In-Reply-To: <20260120081654.1639138-1-tariqt@nvidia.com>
From: Shay Drory <shayd@nvidia.com>
The capability check for reset_root_to_default was inverted, causing
the function to return -EOPNOTSUPP when the capability IS supported,
rather than when it is NOT supported.
Fix the capability check condition.
Fixes: 3c9c34c32bc6 ("net/mlx5: fs, Command to control TX flow table root")
