The chaddr field is 16 bytes long, but that just leaves room for hardware
addresses longer than 6-byte MAC addresses (in a packet with fixed-length
fields - as RFC 951, the BOOTP RFC says, "Fixed length fields of maximum
reasonable length are used to simplify structure definition and parsing,"
presumably for the benefit of boot ROM code); the hlen field indicates how long
that field is (and htype indicates how it should be interpreted).

We could, I guess, tag the 10 bytes following the 6-byte MAC address of the
client as padding.
