Intel Arria 10 - Gigabit Ethernet (Gbe) and Gbe with IEEE 1588 V2

2.6.1. Gigabit Ethernet (GbE) and GbE with IEEE 1588v2
Gigabit Ethernet (GbE) is a high-speed local area network technology that provides
data transfer rates of about 1 Gbps. GbE builds on top of the ethernet protocol, but
increases speed tenfold over Fast Ethernet. IEEE 802.3 defines GbE as an intermediate
(or transition) layer that interfaces various physical media with the media access
control (MAC) in a Gigabit Ethernet system. Gigabit Ethernet PHY shields the MAC
layer from the specific nature of the underlying medium and is divided into three sub-
layers shown in the following figure.
