Only if no VLAN.
When using VLANs it is 4 bytes more. But why do you mind that at all ?
Wasn't one architecture faulting on a double-register read?
Where that had to be aligned (probably 8 bytes) but a normal
memory read could be misaligned?
That was hppa64, and the problem was with its qemu emulation,
not with this code.
