A cable test is performed on all selected ports. The cable test might take up to two
seconds to complete. If the port forms an active link with a device, the cable status is
always Normal.
The test returns a cable length estimate if this feature is supported by the
PHY for the current link speed. Note that if the link is down and a cable is attached to a
10/100 Ethernet adapter then the cable status might be Open or Short because some
Ethernet adapters leave unused wire pairs unterminated or grounded.
