Do you mean to say that the moment we have dequeued the packets , then that's the time we remove it from the list, so that now the next device gets polled, so this way now this particular device gets priority. However what I am puzzled is in the net_rx_action function, if the poll method still have packets in the input queue waiting to be processed we remove the device from the poll_list.
