Please add I really need it

Adding this would allow (maybe with some more features) to use it to build matter compatible devices …

Just wonderfing what's the plan. I dont mind working on it, just dont want to interrupt a development stream if its in progress.
It's of course two parts, one is dgram module, and second is enhancements that are needed in cyw43 if any. And a additional would be examples. I can certianly fork, work it out, and then do a merge. Let me know.

Reviewing the wifi driver side, it looks good to go. Seems just missing dgram module at a glance.
Wondering on max socket limititations.
