One possible answer is that you should keep a set of the ones you've added so
far...
self.macaddrtable = {}
self.macaddrs = set()
...
if (packet.src,packet.dst) not in self.macaddrs:
self.macaddrs.add((packet.src,packet.dst]))
self.macaddrtable[f_id]=(packet.src,packet.dst)
f_id=f_id+1
There might be better things to be done, but it's impossible to say without
knowing more (e.g., what you're trying to accomplish, what f_id is used for,
etc.).
