I don't this this fix is correct, I am able to reproduce the crash in a
hyper-v VM and this generates a different KASAN bad free with the repro
case.
If you want to test (and have an environment with an SRIOV interface), you can
toggle SRIOV rapidly with this powershell snippet:
$vmname= 'name of vm'
while (1){
Set-VMNetworkAdapter -VMName $vmname -IovWeight 100
Set-VMNetworkAdapter -VMName $vmname -IovWeight 0
}
