Xiangqian Zhang f6f2e946aa net: mii: Fix the Speed display when the network cable is not connected ...

Two different models of usb card, the drivers are r8152 and asix. If no
network cable is connected, Speed = 10Mb/s. This problem is repeated in
linux 3.10, 4.19, 5.4, 6.12. This problem also exists on the latest
kernel. Both drivers call mii_ethtool_get_link_ksettings,
but the value of cmd->base.speed in this
function can only be SPEED_1000 or SPEED_100 or SPEED_10.
When the network cable is not connected, set cmd->base.speed
=SPEED_UNKNOWN.
