6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shay Drory <shayd@xxxxxxxxxx>
[ Upstream commit 32966984bee1defd9f5a8f9be274d7c32f911ba1 ]
Currently, MultiPort E-Switch is requesting to create a LAG with shared
FDB without checking the LAG is supporting shared FDB.
Add the check.
Fixes: a32327a3a02c ("net/mlx5: Lag, Control MultiPort E-Switch single FDB mode")
