What were you trying to do that didn't work?
Rss support for virtio-net driver is bad on windows guest, it can not got expect result after run the test.
The test result are as following, but the Errors and Misses expect result should be 0.
DeviceHashSupport=TRUE
DeviceRssOn=TRUE
DeviceRssSupport=TRUE
Errors=147
Hits=830
Misses=0
Unclassified=0

2.Run the command "netkvm-wmi.cmd rss" to collect statistics
> D:\netkvm-wmi.cmd rss

Expected results
Errors and Misses equal to 0
Actual results

Additional info:
1. qemu-kvm-9.0.0-9.el10.x86_64 works well, so this should be a regression bug.
