[lwip-devel] more about SO_REUSE and UDP

[christiaan . simons]

Hi Leon, Kieran,

Leon, there are still some #ifdef's instead of #if's for SO_REUSE in udp.c,
(and the #ifndef can be turned into a #if SO_REUSE == 0).

Or better, can Kieran or Florian indicate if they really need patch #1399?
If it isn't used, and it is not tested, err, why not remove it?
(and keep things really simple and light weight...)

It looks likes the patch changes the behaviour of the PCB API.

A radical idea: maybe the (udp) pcb list could be turned into
some sort of (c++ like) map where only unique entries are stored.

This keeps the list as short as possible, and improves search
speed for unwanted (netbios etc) traffic. Sorting the list as Leon
mentioned previously works for wanted (reference counted) traffic only.

Bye,

Christiaan
