newer controller have a sparce bus space that can be figured out by probing the HW. This gives the starting bus number. When reading the PCI config. space behind the VMD controller, the offset of the starting bus needs to be subtracted from the bus being read. Fixed a bug in which in which not all of the devices directly attached to the VMD controller would be probed. On my initial test HW, a switch was found at bus 0, slot 0 and function 0. All of the NVME drives were behind that switch. Now scan for all slots and functions attached to bus 0. If a something was found then run attach after the scan. On detach also go through all slots and functions on bus 0. Tested with device ID's: 0x201d & 0x9a0b Tested by: nc@ MFC after: 7 days PR: 252253

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
