OK.
~ # modprobe bonding
~ # ethtool bond0
Settings for bond0:
Link detected: no
~ # ifconfig eth1 down
~ # echo +eth1 > /sys/class/net/bond0/bonding/slaves
~ # ethtool bond0
Settings for bond0:
Link detected: *yes*
*Here*, use 'ip link show bond0' we can see the state is *DOWN*, but
the ethtool report is yes, which is wrong.
And then, we do that 'ifconfig bond0 down; ethtool bond0', we get the
wrong report "Link detected: yes".
