Thanks a lot, I think you are right. I got confused between hot-plug of a device on root port, and hot-plug of the root port itself. 

No I'm not bothered about the hot-plug of the host bridge itself. I was talking abouthot-plug of a device directly under the root port.

So I' assuming I should be good with pciehp then.

Thanks,
