Follow-up Comment #1, bug #28064 (project lwip):
I think the simplest solution to solve this is to create macros
(LWIP_ISR_ENTER(), LWIP_ISR_LEAVE()) that increase a counter and let
pbuf_alloc check that counter. Then, these macros would have to be called from
ISRs wanting to use lwIP.
I think allocating pbufs from ISRs is a worthy feature to keep netif drivers
simple.
