MAC Configuration 2 Register (MACCFG2)

Reserved
This field determines the length in bytes of the preamble field preceding each Ethernet start-of-frame
delimiter byte. Values from 0x3 to 0xF are supported by the controller. The default value of 0x7 should
not be altered in order to guarantee reliable operation with IEEE 802.3 compliant hardware.
Reserved
This field determines the type of interface to which the MAC is connected. Its default is 00.

01 Nibble mode (MII, RGMII) (10/100 Mbps MII, RGMII). For RGMII, ECNTRL.RPM should be set to 1.

should be left at its default setting if a user-defined preamble is transmitted.
