From: Zhu Yanjun <yanjun....@windriver.com>
According to the suggestions from Rustad, Mark D, to all the slave
interfaces, the link_speed and link_up should be synchronized since
the time span between link_up and link_speed will make some virtual
NICs not work well, such as a bonding driver in 802.3ad mode.
