I have never seen a 100Mbit MAC with linked DMA buffers which did not support buffers of different sizes...
Some are very restrictive, e.g. AT91SAM7X and AT91SAM9260 (at least) are fixed at 128 bytes per buffer.

This is the PowerQUICC FEC? Then yes the RX buffer size is fixed to the same size for all buffers.
