Hi Justin,
In your reply to scalability question, you answered that we can modify the 
limit of 2K MAC addresses to any value by changing a #define at openvswitch 
code. 
Can you please let me know the file name where I can modify this limit?
Thanks & Regards,Sachin Sharma

There shouldn't be much in the way of hard scalability limits in OVS.  The 
limits we've put in place (e.g., 2K MAC addresses for the learning table in a 
bridge) are typically just a #define, so they can be adjusted fairly easily 
(although they may not be optimized for radically larger values).  However, OVS 
is used in very large, high-density virtualized environments without any 
source-code modification, so it shouldn't be
 necessary with the proper management model.
