Subject: [PATCH mlx5-next 2/2] net/mlx5: IFC, Add capability bits for virtual LAG
Date: Mon, 5 Oct 2026 11:40:47 +0300 [thread overview]
Message-ID: <20261005084047.237081-3-tariqt@nvidia.com> (raw)
In-Reply-To: <20261005084047.237081-1-tariqt@nvidia.com>
From: Shay Drory <shayd@nvidia.com>
Virtual LAG can also be built over virtual uplinks rather than physical
ports.
The support for this virtual LAG is indicated by multi_uplink_eswitch
and port_select_eswitch caps bit.
