The security model values 1 and 2 ("reserved for SNMPv1" and "reserved 

for SNMPv2") in SNMPv3 packets shouldn't cause the security parameters
to be interpreted as a character string - those values are apparently
not supposed to show up in packets - so we handle those values in the
default case, with the security parameters treated as opaque data.
