Function netstack_testing_common::interfaces::wait_for_v4_and_v6_ll

pub async fn wait_for_v4_and_v6_ll(
    interfaces_state: &StateProxy,
    id: u64
) -> Result<(Ipv4Addr, Ipv6Addr)>

Wait until there is an IPv4 and an IPv6 link-local address assigned to the interface identified by id.

If there are multiple IPv4 or multiple IPv6 link-local addresses assigned, the choice of which particular address to return is arbitrary and should not be relied upon.

Note that if a netemul::TestInterface is available, helpers on said type should be preferred over using this function.
