Generic networking device queues drop when the overflow.

Whatever dev->tx_queue_len is set to, the device driver needs
to be prepared to be able to queue successfully.

Most people run into problems when they run stupid UDP applications

either fix the UDP app or restrict it's socket send buffer size.
