[pox-dev] Defining Dictionary in POX controller

[Sayed Qaiser Ali Shah]

Hello everybody,

I have defined dictionary in POX controller and I by the name addrtable and
I am saving two things in this dictionary i.e. Source mac and destination
mac. What I have done is

    self.macaddrtable = {}
...
    f_id=1
    self.macaddrtable[f_id]={packet.src, packet.dst}
    print self.macaddrtable
    f_id=f_id+1

It is saving source mac and destination mac in the dictionary but the
problem is when f_id increases it then save same source and destination mac
again and again.
What I want is to save mac address only if its not in dictionary.
