VT6130 datasheet was wrong. If VT6130 receive a jumbo frame the
controller will split the jumbo frame into multiple RX buffers.
However it seems the hardware always dma the frame to 8 bytes
boundary for the split frames. Only the first part of the fragment
can have 4 byte alignment and subsequent buffers should be 8 bytes
aligned. Change RX buffer the alignment requirement to 8 bytes from
4 bytes.
