New and updated drivers are released through a DSr release. There are two components in a release:
DSr Device Support Matrix
The DSr software is the updated device driver code that is installed onto the Network Configuration Manager installation. DSr is installed independent of the Network Configuration Manager application.
The DSr Device Support Matrix contains a list of all devices that Network Configuration Manager supports through VMware, Inc.-based certification and details the functionality that is supported on the device family.
DSr releases are quarterly based (at the end of the quarter - calendar quarters) and each release is planned in an N+1 manner. There are four (4) DSr releases per year.
