Hi Sayed,
My 2 cents as below..
Just to put Murphy's words into examples- please find below
while initialising the controller, create a mac adde dictionary like below
def __init__(self):
# as soon as the module is hooked initialise..
self.macaddrtable = {}
as and when you get an packet with unknown address you can update the
dictionary based on source mac learning like below
#updating srcmactable
self.updateMap(inport,srcmacaddr)
that will help you keep a dummy src mac able in the controller.
Cheers!
