I objected following behaviour. In this function eth_drv_recv(). When i don't make a broadcast storm (bridge loop) i can allocate everytime a pbuf. Most of the time the device survives the first storm and is availible after releasing the storm. I can't allocate pbuf when i redo the boradcast storm several times. Then i get for pbuf_alloc() = zero. No i call everytime when i can't alloc pbuf for my ethernet device pbuf_init() in the function eth_drv_recv(). It seems that my device is responding now and can alloc pbufs again. But still not perfect. This means not at full bandwith for example i can't open more than 1 socket the other ones get rejected. What can i do to make a clean buffer/pbuf reset of the stack? A broadcast storm is a error state so i want to clear all packets which were send throug.
