Does chutney need to test various rare IPv6/IPv4 combinations?

We could make sure that legacy/trac#16954 (moved) enables the following combinations:

• IPv6 bridge client - IPv6 bridge -- ---- hs

• IPv6 bridge client - IPv6 bridge -- IPv6-only Exit

• IPv6 bridge client - IPv6 bridge -- IPv6/IPv4 Exit

• IPv6 bridge client - IPv6 bridge -- IPv4 Exit

• IPv4 bridge client - IPv4 bridge -- IPv6-only Exit

• IPv4 bridge client - IPv4 bridge -- IPv6/IPv4 Exit This probably also depends on legacy/trac#17011 (moved).

• IPv4 client --- IPv6-only Exit

• IPv4 client --- IPv6/IPv4 Exit
