yttrium-virtio-gpu/NetKVM/NotifyObject

Notify object of VIOPROT protocol supported by NETKVM

The notify object runs on protocol installation (it checks all the existing adapters) and on installation of new adapter (it checks the new adapter):

If the adapter's PnP ID matches the list of supported ones, the notify object unbinds it from all the protocols and binds only to VIOPROT. It there is NETKVM adapter with the MAC address identical to one of checked netwrok adapter, these 2 adapters with the same MAC address will be 'teamed' (subject to compatibility check) and the NETKVM uses the teamed adapter for RX and TX.

Protocol installation

(by admin, from the directory where vioprot.inf is located)

netcfg -v -l vioprot.inf -c p -i VIOPROT

Protocol uninstallation (example of the batch):

netcfg -v -u VIOPROT
timeout /t 3
for %%f in (c:\windows\inf\oem*.inf) do call :checkinf %%f
echo Done
timeout /t 3
goto :eof
:checkinf
type %1 | findstr /i vioprot.cat
if not errorlevel 1 goto :removeinf
echo %1 is not VIOPROT inf file
goto :eof
:removeinf
echo This is VIOPROT inf file
pnputil /d "%~nx1"
timeout /t 2
goto :eof
