[lwip-devel] [bug #2595] loopif results in NULL reference for incoming TCP packets

[Simon Goldschmidt]

Follow-up Comment #19, bug #2595 (project lwip):

RE comment #18:

The two patches (file #12510/12511) will work, but creating an own thread is
not really necessary. It is easier to create a simple linked list of pbufs
and call something like loopif_poll() in the main lwip loop (loopif_poll
would call netif->input() for every packet in the linked list.

That way, you save yourself from having an additional thread (which saves
context-switches and thus, time) and a linked list will be way faster than
sys_mbox_t. Also, it's compatible both with NO_SYS=1 and NO_SYS=0.
