Details:


In order to receive IPv6 link-local multicast packets on certain Wi-Fi
interfaces, we need to explicitly set the filter for it.

One could set it when the interface is added to lwIP, but it turns out that
sometimes the Wi-Fi chip would need to be reset after the interface has been
added.  In such case, the filters would need to be populated again.  

As a result, we propose this patch, which would add the link-local address to
the filter whenever we confirm the assignment of an IPv6 address to the
interface.
