There are other instances of similar weird identical statements guarded
by the test on the board type being DAYNA.

For example, in cops_send_packet():

	if(lp->board == DAYNA)
               	outb(skb->len >> 8, ioaddr);
	else
		outb((skb->len >> 8)&0x0FF, ioaddr);

Could you scan the rest of the driver and deal with all of these
instances in one go?

Thank you!
