[PATCH v3 4/4] PCI: hotplug: Add quirk For Dell nvme pcie switches

2019-04-19 Thread Alexandru Gagniuc
These switches are used to fornicate the motherboard's x16 PCIe ports into four x4 ports for NVMe drives. In conjunction with the storage backplane, the PDS bit reports only the out-of-band presence. The fact that inband presence is disabled is not reported in the slot capabilities 2 (SLTCAP2)
