network - Increase MSIZE to 512
* The basic problem with 384 is that kmalloc() may hand back a buffer
which crosses a page boundary, which gums up the DMA engines for
numerous drivers. Many drivers can only handle one segment per
mbuf and even those that can handle more sometimes have fairly low
segment count limits.
