No. PCI secondary bus reset = PCIe Hot Reset. Slot reset is just another
type of reset, which is currently implemented only for PCIe hot plug
bridges and for PowerPC PowerNV platform and it just call PCI secondary
bus reset with some other hook. PCIe Warm Reset does not have API in
kernel and therefore drivers do not export this type of reset via any
kernel function (yet).
