After any operation that downloads a file (e.g., pxe get, or dhcp), the buffer containing the downloaded data is flushed. This is unnecessary and annoying. Unnecessary, because the network driver should already have fliushed the cache for the DMAed area, and annoying because it generates a cache misalignment message.
