although LLDP is using internal classes, no class is registered into
'_class_prefixes'.
therefore, from_jsondict() does not work correctly.
this patch makes from_jsondict() to work correctly by registering internal
classes into '_class_prefixes'.
examination code:
from ryu.lib.packet import lldp
msg1 = lldp.lldp([lldp.ChassisID(subtype=lldp.ChassisID.SUB_MAC_ADDRESS,
chassis_id='\x00\x00\x00\x00\x00\x00')])
print msg1
jsondict = msg1.to_jsondict()
msg2 = lldp.lldp.from_jsondict(jsondict['lldp'])
print msg2
print str(msg1) == str(msg2)
before applying this patch:
lldp(tlvs=[ChassisID(chassis_id='\x00\x00\x00\x00\x00\x00',len=7,subtype=4,typelen=519)])
lldp(tlvs=[{'ChassisID': {'subtype': 4, 'typelen': 519, 'chassis_id':
'\x00\x00\x00\x00\x00\x00', 'len': 7}}])
False
after applying this patch:
lldp(tlvs=[ChassisID(chassis_id='\x00\x00\x00\x00\x00\x00',len=7,subtype=4,typelen=519)])
lldp(tlvs=[ChassisID(chassis_id='\x00\x00\x00\x00\x00\x00',len=7,subtype=4,typelen=519)])
True
