Latest upstream QEMU has fixed its memory handling so that MMIO regions do not need to be a multiple of page size. Changing RTL8139 to use a block of size 0x1000 is a reasonable short term hack around the problem, but syncing with latest QEMU is the real solution, since there are other places in the code which will have similar issues.
