This is dependent on the MAC and/or PHY behaviour. +``PHY_INTERFACE_MODE_10GBASER`` + This is the IEEE 802.3 Clause 49 defined 10GBASE-R protocol used with + various different mediums. Please refer to the IEEE standard for a + definition of this. + + Note: 10GBASE-R is just one protocol that can be used with XFI and SFI. + XFI and SFI permit multiple protocols over a single SERDES lane, and + also defines the electrical characteristics of the signals with a host + compliance board plugged into the host XFP/SFP connector.
