No, this is a software loopback.

You can test the DS80C400-PHY communication using the ReadMII call, e.g.
TININet.ReadMII(phy, MII_PHY_ID_HI) should be 0x0013
TININet.ReadMII(phy, MII_PHY_ID_LO) & 0xfff0 should be 0x78e0

where
MII_PHY_ID_HI   2
MII_PHY_ID_LO   3
and phy is probably 0.

The link and activity LEDs are independent of any software running on
the DS80c400; the LEDs should indicate activity as soon as you connect
the network.
