lwip recvfrom in interrupt handler

[Maurizio2]

Is it possibile use lwip_recvfrom inside the interrupt handler? In my application I use FreeRtos and LWIp. The recvfrom is in non blocking mode but the function not return (the Queue inside LWIP are xQueueReceive  without FromISR).

Is there a lwip_recvfrom for interrupt handler?

Thanks very much.

ISRs should be short and fast. lwip_recvfrom() is relatively heavy and may cause issues on the application. I do not suggest using it inside the ISR.
