Series selftests: Preparations for out-of-order-operations patches in mlxsw | expand

Commit Message

Petr Machata June 20, 2023, 1:55 p.m. UTC 
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.
