Commit Message

handle remoteIp delete properly

There are 2 ways to delete a remoteIp
1. send update / replace for the remoteEp without the remoteIp

Is handled correctly because the notif code gets the correct
remoteEp Mo which then triggers the remoteEp update

2. delete the remoteIp alone

This case is not handled today. there is no listener to this update
so no notif happens.

Based on the logs CSCvx60417 / 	690770038 this is whats happening here.

This is normally not an issue if the same remoteIp is updated later,
in this case the remoteIp is a VIP. But if the VIP to VTEP mapping
changes and update does not come through we end up with a flow
for the VIP thats using a stale VTEP.

This fix ensures we handle this case and delete the stale flow
right away, any time you see this log

[2021-Mar-25 22:41:12.968729] [debug] [Processor.cpp:524:processItem] Purging state for /InvUniverse/InvRemoteEndpointInventory/InvRemoteInventoryEp/2f40f94e-6d15-490a-ae36-cdaf21862d59%7cfa-16-3e-6b-03-cf/InvRemoteIp/10.60.30.250/ in state remote

Even if update does not come, the flow table is consistent and the worst that
will happen is the packet that should use the new mapping from the VIP -> new VTEP
ends up going to leaf where its forwarded correctly in the absense of the stale flow.
