At the time that the front panel port is enslaved to the bridge (this holds for both bridges used here), the bridge MAC address does not have the same prefix as other interfaces in the system. On Nvidia Spectrum-1 machines all the RIFs have to have the same 38-bit MAC address prefix. Since the bridge does not obey this limitation, the RIF cannot be created, and the enslavement attempt is vetoed on the grounds of the configuration not being offloadable. The selftest itself however checks traffic prioritization and scheduling, and the bridges serve for their L2 forwarding capabilities, and do not need to participate in routing traffic. The IP addresses or the RIFs are irrelevant. Fix by disabling automatic IPv6 address generation for the HW-offloaded bridges in this selftest, thus exempting them from mlxsw router attention.
