Comment 1 Yvugenfi@redhat.com 2019-10-22 08:20:34 UTC

https://github.com/virtio-win/kvm-guest-drivers-windows/pull/406

1. There was a typo in the parameter name shown to the user.

2. In general "TesOnly.X" parameters are not shown to the user and can only be set by changing registry directly. It was done in order not to confuse the users with debug settings. For some reason "TesOnly.RXThrottle" was kept in INF.

3. The fix removes "TesOnly.RXThrottle" from the GUI settings. It still can be set in the registry if needed.

4. The verification after the fix should test that the "TesOnly.RXThrottle" is not shown in the device manager after the driver is installed.

Comment 2 Yu Wang 2019-12-13 09:20:22 UTC

Verified on latest driver (virtio-win-prewhql-174)
Guest OS: win7-74, win8-32, win2016 and win2019

"TesOnly.RXThrottle" is not shown in the device manager and  no "NumberOfHandledRXPackersInDPC" after typing "netsh netkvm show parameters name"

So this bug has been fixed , I will change it to verified.


Thanks
Yu Wang
