although IPv6 is using internal classes, no class is registered into
'_class_prefixes'.
therefore, AssertionError occurs in from_jsondict() when the argument
'ext_hdrs' was processed.
this patch makes from_jsondict() to work correctly by registering internal
classes into '_class_prefixes'.
examination code:
from ryu.lib.packet import ipv6
msg1 = ipv6.ipv6(ext_hdrs=[ipv6.hop_opts()])
print msg1
jsondict = msg1.to_jsondict()
msg2 = ipv6.ipv6.from_jsondict(jsondict['ipv6'])
print msg2
print str(msg1) == str(msg2)
before applying this patch:
ipv6(dst='::',ext_hdrs=[hop_opts(data=None,nxt=6,size=0)],flow_label=0,hop_limit=255,nxt=6,payload_length=0,src='::',traffic_class=0,version=6)
