/**
* Inputs a new packet into the system
* This function is called from interface drivers ISR to route and accept packets.
* But it can also be called from a task, provided that the pxTaskWoken parameter is NULL!
*
* EXTREMELY IMPORTANT:
* pxTaskWoken arg must ALWAYS be NULL if called from task,
* and ALWAYS be NON NULL if called from ISR!
* If this condition is met, this call is completely thread-safe
*
* This function is fire and forget, it returns void, meaning
* that a packet will always be either accepted or dropped
* so the memory will always be freed.
*
* @param packet A pointer to the incoming packet
* @param interface A pointer to the incoming interface TX function.
* @param pxTaskWoken This must be a pointer a valid variable if called from ISR or NULL otherwise!
