[nsp] Duplex issues with 4700

[Krzysztof Adamski]

It's the "Unknown duplex" at the end of this:
Ethernet0 is up, line protocol is up
  Hardware is Am79c970, address is 0010.7b47.039a (bia 0010.7b47.039a)
  Internet address is 6.35.18.16/27
  MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Unknown duplex
^^^^^^^^^^^^^^^^^

that has me concerned, I have already changed the cables and I'm seeing a
1 to 3% loss on 1000 pings.
