Can anyone advise on SYS_LIGHTWEIGHT_PROT, please?
SYS_LIGHTWEIGHT_PROT should be set to 1 if you are using pbufs or
memp-pools from different execution contexts (e.g. more than one thread
or interrupt context). The name is somewhat misleading as 0 does not
lead to 'heavyweight' protection but no protection at all! This is
useful when running the stack with NO_SYS=1 in a big loop without
(de-)allocating pbufs from interrupt context (-> only one execution
context at all).
