[lwip-devel] [bug #3168] Handling UDP/TCP PCBs upon netif address change.

[Simon Goldschmidt]

Follow-up Comment #7, bug #3168 (project lwip):

Since for TCP pcbs, a call to pcb->recv() with a pbuf p=NULL means the
connection is closed, I propose to do it that way for UDP pcbs on netif
address change.

I'll attach a patch as a first draft.

Note that the comment in netif_set_ipaddr() can be removed and the
documentation (doc/rawapi.txt) must be updated (a notification mail to
lwip-users would be good as well).

Last, the core stack and the ports in contrib should be updated to test p
against null in all udp_pcv->recv() callbacks.
