[lwip-devel] [bug #19347] netif_add & tcpip_init problem

[Simon Goldschmidt]

Follow-up Comment #35, bug #19347 (project lwip):

Any comments on patch file #12404 (automatically starting/stopping the dhcp
timers on dhcp_start/stop())?

On the one hand, it saves us the starting the timer ourselves and saves us
from a running timer if there's no netif with dhcp. On the other hand,
dhcp_start must be called from tcpip_thread(), so can't be called when
initializing the stack (either before OS is started or from another thread).
Or you have to use netifapi_dhcp_start()/stop().

I think this would be a good patch (combined with a define-switch included in
opt.h and a good documentation in a new file called multithreading.txt :)
