v6:
 - remove (S0_TX_FSR < skb->len) check in TX handler, it doesn't work
   anyway. Chip can transmit only one frame with MTU 1500 at a time,
   and tx buffer size is bigger.

So what happens if XXX frames are given to start_xmit() in a flood ?

You removed any flow control, how can this work ?

Device has an infinite queue ?
