Traceback (most recent call last):

File "/usr/local/lib/python3.5/dist-packages/swsssdk-2.0.1-py3.5.egg/swsssdk/configdb.py", line 284, in get_config
(table_name, row) = key.split(self.TABLE_NAME_SEPARATOR, 1)
TypeError: a bytes-like object is required, not 'str'

FIX:
Current code:
for key in keys:
try:
(table_name, row) = key.split(self.TABLE_NAME_SEPARATOR, 1)

Proposed code change:
for key in keys:
if PY3K:
key = key.decode('utf-8')
try:
(table_name, row) = key.split(self.TABLE_NAME_SEPARATOR, 1)
