[ Upstream commit 216214c64a8c1cb9078c2c0aec7bb4a2f8e75397 ]
Flow table that contains flow pointing to multiple flow tables or multiple TIRs must have a level lower than 64. In our case it applies to muli- destination flow table. Fix the level of the created table to comply with HW Spec definitions, and still make sure that its level lower than SW-owned tables, so that it would be possible to point from the multi-destination FW table to SW tables.
