10GBASE-R is a single-channel protocol that runs independently. You can configure
the transceivers to implement 10GBASE-R PHY functionality by using the presets of
the Native PHY IP. The complete PCS and PHY solutions can be used to interface with a
third-party PHY MAC layer as well.
The following 10GBASE-R variants area available from presets:
• 10GBASE-R
• 10GBASE-R Low Latency
• 10GBASE-R Register Mode
Intel recommends that you use the presets for selecting the suitable 10GBASE-R
variants directly if you are configuring through the Native PHY IP core.
