Subject: [PATCH net-next 13/15] net/mlx5: E-Switch, defer rep load while SD LAG is not active
Date: Thu, 4 Jun 2026 14:44:53 +0300	[thread overview]
Message-ID: <20260604114455.434711-14-tariqt@nvidia.com> (raw)
In-Reply-To: <20260604114455.434711-1-tariqt@nvidia.com>

From: Shay Drory <shayd@nvidia.com>

On an SD device, vport representors are not functional until the SD
group is combined and shared FDB is active. Skip both the initial load
and the reload path in that window; reps are loaded as part of the SD
LAG activation flow once it becomes active.
