While investigating the capabilities of BCM63XX's integrated switch and its DMA engine, I noticed a few issues in b53's jumbo frame code. Mostly a confusion of MTU vs frame length, but also a few missing cases for 100M switches. Tested on BCM63XX and BCM53115 with intel 1G and realtek 1G NICs, which support MTUs of 9000 or slightly above, but significantly less than the 9716/9720 supported by BCM53115, so I couldn't verify the actual maximum frame length.
