For plugins built before NVDK 7.0 Update 1, the update and remove procedures are the same as before.
For newer plugins, we have a simpler procedure that does not require rebooting the ESX host.
As of vSphere 7.0 Update 1, vendors can deliver a NAS VAAI plug-in that does not require ESXi reboot to be installed or removed. However, when replacing an older NAS VAAI plug-in, host reboot will be required for removal, because internally those plug-ins specify LIVE_REMOVE_ALLOWED=false.
