ARP message padding

Hi list!

Whilst working on the IPv4LL part of dhcpcd, I was wondering why some frames I 
was capturing were 60 bytes and some were 42 - which was the size I was 
expecting. After some research, I find about minimum ethernet frame size 
which is 64, including the 4 byte crc.

I'm asking this here, because NetBSD sends a gratuitous ARP when assinging and 
address to an interface, which is 42 bytes in length according to my capture. 
This is also what dhcpcd currently does.

So the question is, should both pad up to 60?
