Sure, it works fine if I rename the table, or just switch the protocol
to a different one. But, erm, it shouldn't crash even if I don't, should
it? In the worst case it should refuse the reconfigure...

Feels like it's a pretty natural thing to decide "I want ipv6 sadr
routes now, let's just change every instance of 'ipv6' to 'ipv6 sadr'"
and expect it to work :)
