In a future patch, mlxsw will start adding RIFs to uppers of front panel port netdevices, if they have an IP address. This will cause this selftest to fail spuriously. The swp enslavement to the 802.1ad bridge is not allowed, because RIFs are not allowed to be created for 802.1ad bridges, but the address indicates one needs to be created. Fix by disabling automatic IPv6 address generation for the HW-offloaded bridge in this selftest, thus exempting it from mlxsw router attention.
