I ran my tests I didn't notice any problems deleting a full VLAN

my cover letter - the complexity is not worth it, so I dropped that
patch.
For the 79ms number - how big was the system and was it busy?
It was a VM with 3 vCPUs, not load. The baseline (without patches) was ~25%
faster.
This is still a slow path and deleting 4k VLANs is not a common thing. :)
Note that flushing all VLANs usually happens when a port is being deleted and
that is still fast as before (it doesn't wait a gp for every VLAN).
