Maximum Receive Frame Control Register (DMARFC)
The DMARFC defines the maximum frame length for a received frame that can be stored in the
system memory. It is recommend that only use this register while S/W wants to receive a frame which
length is greater than 1518 bytes.

DESCRIPTIONS
-
The Maximum Receive Frame Length defines the
maximum frame length for received frame. If the frame
length of received frame is greater than RXMS, and bit
EnDFO of MIEN register is also enabled, the bit DFOI of
MISTA register is set and the Rx interrupt is triggered.
It is recommended that only use RXMS to qualify the length
of received frame while S/W wants to receive a frame which
length is greater than 1518 bytes.
