[ns] Mobiwan: how are the classifiers configured after getting a new coa

[Kong Ruoshan]

Hi all,

In the Mobiwan, when a MN receives a RADS message from a new BS, it will get a new coa. I believe the MN's classifier_hier_ will be configured after that so that it will send those packets (destined to coa) to the port classifier.

With gdb, I made a test. After getting the new coa, MN sent BU to HA, and received BACK message. The BACK's destination address was the coa, and it passed the MN's classifier_hier_ and reached the port classifier. So I believe the classifier_hier_ did be configured after getting coa and before receiving BACK.

However, I read the code but could not find how the MN's classifier_hier_ was configured. Where can I find the exact code?
