In a future patch, mlxsw will start adding RIFs to uppers of front panel port netdevices, if they have an IP address. At the time that the front panel port is enslaved to the bridge, 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 how many mirroring sessions a machine is capable of offloading. The IP address or the RIF are irrelevant. Fix by disabling automatic IPv6 address generation for the HW-offloaded bridge in this selftest, thus exempting it from mlxsw router attention.
