The DHCOM does ship with KS8851 with 1.5 kiB packet buffer. The DHSOM may be extended with other MAC options connected to FMC2 bus, like the DM9000, wih similar limitations. Use default CONFIG_TFTP_BLOCKSIZE of 1468 Bytes instead of 1536 Bytes, which always avoids overflowing the packet buffers of such limited MACs, which leads to e.g. TFTP timeouts. This also avoids receiving a short packet fragment at the end of each TFTP block, which led to reduced performance.
