Changed a VXLAN Identifier for single VN...IFL delete/add seen for all the existing IFLs

[Anoop Kumar Sahu]

I changed a VXLAN identifier for a single Virtual Network. When looked at ovsdbdatase, the churn is seen for all the existing IFLs(2K in my case). Optimization needed here ..

With 1 vlan-port binding, changed vxlan from 4 to 400. We see only 1 update sent from tor-agent to the TOR i.e. only the logical-switch update and no lif update.

Can you check on qfx ?
