If you mean the "big loop" before checking the ethernet driver and 
feeding packets to the ip_input or calling timers, yes, that's OK. You 
only have to make sure that no other task or interrupt context can get 
active in lwIP at the same time. With the simple "big loop" examples 
(e.g. in the win32 port), it's OK like that.
