This is understood.

However, the point which is still not clear to me related to the LAG /
switchdev object model.

All of FDB/VLAN/FIB switchdev objects have corresponding software counterparts
in the kernel --- what's the case for LAG? the software construct is
bond or team
instance, shouldn't there  be a modeling of the HW LAG object in switchdev?

Or.
