If anyone has any objections, please let me know. ------------------ From: Carolina Jubran [ Upstream commit e92df790d07a8eea873efcb84776e7b71f81c7d5 ] mlx5_eswitch_get_vepa returns -EPERM if the device lacks eswitch_manager capability, blocking mlx5e_bridge_getlink from retrieving VEPA mode. Since mlx5e_bridge_getlink implements ndo_bridge_getlink, returning -EPERM causes bridge link show to fail instead of skipping devices without this capability. To avoid this, return -EOPNOTSUPP from mlx5e_bridge_getlink when mlx5_eswitch_get_vepa fails, ensuring the command continues processing other devices while ignoring those without the necessary capability.
