[lwip-devel] [task #6995] Implement SO_REUSEADDR

[Simon Goldschmidt]

Follow-up Comment #2, task #6995 (project lwip):

Some more notes:

- udp_bind does currently not check for multiple binding, which looks like a
bug to me! This was disabled because it prevented binding multiple pcbs to a
local multicast address. I think that should be changed.

- when incoming packets are for multicast, udp_input should call the recv
function for all udp_pcbs listening to that port & address. Currently, only
the first pcb in the list will receive the data...
