net/mlx5: LAG, extend shared FDB API with group_id filter

Browse source

Add a group_id parameter to mlx5_lag_shared_fdb_create() and
mlx5_lag_shared_fdb_destroy() to scope shared FDB operations to a
specific SD group.

When group_id is U32_MAX, the functions operate on all LAG devices. When
group_id is non-zero, they operate only on devices in that SD group
without issuing FW LAG commands, since SD LAG is a pure software
construct.
