[lwip-members] RFC: decoupling of raw / netcon_ interface

[leon . woestenberg]

Dear all,

recent patches have changed behaviour of the core lwIP functionality or its
raw API
and have broken it for applications built on it.

Two examples are the change of byte order in the udp_recv() callback, and
the
addition of local address binding in udp_connect().

Apparently I am one of few using the raw API of lwIP.

I would strongly like to decouple the core lwIP/raw API from any higher
layer
socket functionality (like netcon) and void any hacks in the core that
facilitate
features in one or other socket layer wherever possible.

Pls. try to resolve any issues in the upper layers, unless core lwIP is
broken in
some respect.

If changing behaviour or API of any layer is necessary, pls. discuss it on
this
list first.

I would like to undo the udp_recv() and udp_connect() changes and have
those
performed in netcon_*() instead.

Furthermore, I still don't see what the UDP_CONNECTED flag actually does...
Unless this is really needed for lwIP in general, I would like to revert
this as well.

Please discuss these issues on address@hidden

Thanks!
