RFLR is a 32-bit readable/writable register that specifies the maximum frame length (in bytes)
that can be received by this LSI. The settings in this register must not be changed while the
receiving function is enabled.

These bits are always read as 0. The write value should
always be 0.
The frame data described here refers to all fields from the
destination address up to the CRC data. Frame contents from
the destination address up to the data are actually transferred
to memory. CRC data is not included in the transfer. When
data that exceeds the specified value is received, the part of
data that exceeds the specified value is discarded.
