Each FMan has several MACs, each implementing an Ethernet interface. Earlier
versions of FMan used the Datapath Three Speed Ethernet Controller (dTSEC) for
10/100/1000 MBit/s speeds, and the 10-Gigabit Ethernet Media Access Controller
(10GEC) for 10 Gbit/s speeds. Later versions of FMan use the Multirate
Ethernet Media Access Controller (mEMAC) to handle all speeds.

DESCRIPTION Refer to Documentation/devicetree/bindings/net/fsl,fman-dtsec.yaml
mEMAC/dTSEC/XGEC are the Ethernet network interfaces
PROPERTIES
- compatible
Usage: required
Value type: <stringlist>
Definition: A standard property.
Must include one of the following:
- "fsl,fman-dtsec" for dTSEC MAC
- "fsl,fman-xgec" for XGEC MAC
- "fsl,fman-memac" for mEMAC MAC
- cell-index
Usage: required
Value type: <u32>
Definition: Specifies the MAC id.
The cell-index value may be used by the FMan or the SoC, to
identify the MAC unit in the FMan (or SoC) memory map.
In the tables below there's a description of the cell-index
use, there are two tables, one describes the use of cell-index
by the FMan, the second describes the use by the SoC:
1. FMan Registers
