[lwip-devel] [patch #8755] Multicast DNS responder support

[Erik Ekman]

Follow-up Comment #10, patch #8755 (project lwip):

>> Notifications on IP address changes/additions/removals. 
>> They need to be announced to the peers, checked for conflicts etc.

>That sounds like a deep integration into the stack, as even the current
status callback does not provide information on what was
>changed that triggered the callback (e.g. old address if IPv4 address was
changed). 

It will be enough to know that something changed, and then tell the network
what the current addresses are.
This data is sent with a cache-flush instruction so it replaces earlier
information.
