 2 is harder to answer - I don't understand the comment in if_vge.c:1042 at
 all. How would 32bit alignment of the rx buffer make the received data
 unaligned? What does the chip prepend to the data and what size is it?
 
 1 is easier: ETHER_ALIGN is a define in if_vgevar.h and it's wrong. It probably
 was 2 on FreeBSD (for the two bytes the VGE_FIXUP_RX moves the buffer content
 around) and someone eroneosly changed it to 0 for NetBSD.
