iana: HWType is 16 bits
In both ARP and DHCPv6, the hwtype field is 16bits, and the IANA table
has allocated values >255.
(Bootp however uses 1byte so it can't represent everything)
This was discovered by fuzzing, as it causes round-trip mismatches; eg
with this packet (quoted string):
"0000\x00\x01\x00\x0e\x00\x01000000000000"
Input: 303030300001000e0001303030303030303030303030
Round-trip: 303030300001000e0001003030303030303030303030
^
The upper byte of the hwaddress is set
to 0
