\| \| \| \| \| \| \| \| \| \| \| \| \|	Add the dependency on pci explicitly for the pcib and vmbus drivers. The related Makefiles are updated accordingly too. Reviewed by: sephe Approved by: sephe (mentor) MFC after: 1 week Sponsored by: Microsoft Notes: svn path=/head/; revision=308793
*	hyperv/pcib: enable PCIe pass-through (a.k.a. Discrete Device Assignment)	Dexuan Cui	2016-11-16	1	-0/+12
	The feature enables us to pass through physical PCIe devices to FreeBSD VM running on Hyper-V (Windows Server 2016) to get near-native performance with low CPU utilization. The patch implements a PCI bridge driver to support the feature: 1) The pcib driver talks to the host to discover device(s) and presents the device(s) to FreeBSD's pci driver via PCI configuration space (note: to access the configuration space, we don't use the standard I/O port 0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V, which is very similar to the 0xCF8/CFC method). 2) The pcib driver allocates resources for the device(s) and initialize the related BARs, when the device driver's attach method is invoked; 3) The pcib driver talks to the host to create MSI/MSI-X interrupt remapping between the guest and the host; 4) The pcib driver supports device hot add/remove.
