NetKVM WMI interface (netkvm wmi.cmd)

netkvm-wmi.cmd is a simple developer-oriented tool that allows access to NetKVM driver to query or control the behavior of the driver.

It is based on WMI interface of the network driver: WMI commands are converted to custom OID that the OS sends to the NetKVM driver.

In case of multiple NetKVM devices (multiple network adapters) each command of the netkvm-wmi.cmd is executed for all the devices.

Examples of most useful commands are:

• netkvm-wmi.cmd debug 1: sets logging level of the driver to 1 at runtime
• netkvm-wmi.cmd stat: returns run-time statistics of the adapters
• netkvm-wmi.cmd rss: returns run-time RSS statistics of the adapters (and resets it)
• netkvm-wmi.cmd qfo: returns status of NetKVM failover feature of the adapters

For all the available commands run netkvm-wmi.cmd without parameters. To add new commands for development/testing purposes see the implementation of existing WMI commands:
