net/mlx5: Lag, decouple FDB selection and shared FDB
Multiport eswitch is required to use native FDB selection instead of affinity, This was achieved by passing the shared_fdb flag down the HW lag creation path. While it did accomplish the goal of setting FDB selection mode to native, it had the side effect of also creating a shared FDB configuration. This created a few issues: - TC rules are inserted into a non active FDB, which means traffic isn't offloaded as all traffic will reach only a single FDB. - All wire traffic is treated as if a single physical port received it; while this is true for a bond configuration, this shouldn't be the case for multiport eswitch. Create a new flag MLX5_LAG_MODE_FLAG_FDB_SEL_MODE_NATIVE to indicate what FDB selection mode should be used.
