Subject: [PATCH] ucc_geth: Intialize link state to down before register_netdev

From: Cliff Clark <cliff_clark@...inc.com>

ucc_geth was indicating link up after a port is administratively enabled even
when nothing is plugged in.  This causes user-space tools to see a spurious link
up the first time after boot.
