HP Auto MDI/MDI-X
HP Auto MDI/MDI-X configuration eliminates the confusion of whether to use a straight cable or a crossover cable
between the KSZ8041TL/FTL and its link partner. This feature allows the KSZ8041TL/FTL to use either type of cable to
connect with a link partner that is in either MDI or MDI-X mode. The auto-sense function detects transmit and receive
pairs from the link partner, and then assigns transmit and receive pairs of the KSZ8041TL/FTL accordingly.
HP Auto MDI/MDI-X is enabled by default. It is disabled by writing a one to register 1F bit 13. MDI and MDI-X mode is
selected by register 1F bit 14 if HP Auto MDI/MDI-X is disabled.
An isolation transformer with symmetrical transmit and receive data paths is recommended to support auto MDI/MDI-X.
The IEEE 802.3u Standard defines MDI and MDI-X as follow:

Straight Cable
A straight cable connects a MDI device to a MDI-X device, or a MDI-X device to a MDI device. The following diagram
depicts a typical straight cable connection between a NIC card (MDI) and a switch, or hub (MDI-X).
