RE: [Xen-devel] Can we disable secondary_bus_reset in runtime?

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

Yes.  I plugged a 82541PI NIC(01:00.0) into motherborad  and tested the 
SecondaryBusReset against 00:1e.0.
(Please see the below for the PCI hierarchy of my host)

And actually the same python function was tested on many hosts by our QA. No 
issue is reported about it.
I haven't received other issue report before you. :-)
Your host is also DQ35?  What is the details of the issue?

Dexuan,

Have you ever try/test the secondary bus reset on any NIC?

Thanks,
Neo

I would remember that if researchers were not ambitious
probably today we haven't the technology we are using!
