The 1000 Base-X PHY is defined by IEEE 802.3 standard as an intermediate or
transition layer that interfaces various physical media with the media access control
(MAC) in a GbE system. The 1000 Base-X PHY, which has a physical interface data
rate of 1.25 Gbps consists of the PCS, PMA, and physical media dependent (PMD)
layers.

(1) CSMA/CD = Carrier-Sense Multiple Access with Collision Detection
(2) GMII = gigabit medium independent interface
