Description
 In BASE-T: Media Dependent Interface[0]:
 1000BASE-T: In MDI configuration, MDI[0]+/-
corresponds to BI_DA+/- and in MDI-X configu-
ration MDI[0]+/- corresponds to BI_DB+/-.
 10BASE-T and 100BASE-TX: In MDI configura-
tion, MDI[0]+/- is used for the transmit pair and in
MDIX configuration MDI[0]+/- is used for the
receive pair.
