>Description:
Unfortunately the tlp0 interface (tulip) doesn't work as expected.
That is change failed to idle.


My tlp0 output.
  tlp0 at pci0 dev 9 function 0: DECchip 21143 Ethernet, pass 3.0
  tlp0: interrupting at irq 9
  tlp0: Ethernet address 00:10:57:c0:07:88

>How-To-Repeat:
# ifconfig tlp0 192.168.1.100
tlp0: transmit process failed to idle: state RUNNING - READING
tlp0: receive process failed to idle: state RUNNING - CHECK
tlp0: transmit process stopped
tlp0: receive process stopped
tlp0: transmit process failed to idle: state RUNNING - READING
tlp0: receive process failed to idle: state RUNNING - CHECK
tlp0: transmit process stopped
      .
      .
      .

>Fix:
I saw source-code of Linux of netwinder.  Their tulip used memory space
(0x00800000).  But, our NetBSD/netwinder used I/O space.  We should also
use the memory space.
