pci: keep a stubDriver in each virPCIDevice This can be set when the virPCIDevice is created and placed on a list, then used later when traversing the list to determine which stub driver to bind/unbind for managed devices. The existing Detach and Attach functions' signatures haven't been changed (they still accept a stub driver name in the arg list), but if the arg list has NULL for stub driver and one is available in the device's object, that will be used. (we may later deprecate and remove the arg from those functions).

pci: autolearn name of stub driver, remove from arglist virPCIDeviceReattach and virPCIDeviceUnbindFromStub (called by virPCIDeviceReattach) had previously required the name of the stub driver as input. This is unnecessary, because the name of the driver the device is currently bound to can be found by looking at the link: /sys/bus/pci/dddd:bb:ss.ff/driver Instead of requiring that the name of the expected stub driver name and only unbinding if that one name is matched, we no longer take a driver name in the arglist for either of these functions. virPCIDeviceUnbindFromStub just compares the name of the currently bound driver to a list of "well known" stubs (right now contains "pci-stub" and "vfio-pci" for qemu, and "pciback" for xen), and only performs the unbind if it's one of those devices. This allows virsh nodedevice-reattach to work properly across a libvirtd restart, and fixes a couple of cases where we were erroneously still hard-coding "pci-stub" as the drive name. For some unknown reason, virPCIDeviceReattach had been calling modprobe on the stub driver prior to unbinding the device. This was problematic because we no longer know the name of the stub driver in that function. However, it is pointless to probe for the stub driver at that time anyway - because the device is bound to the stub driver, we are guaranteed that it is already loaded, and so that call to modprobe has been removed.

The only way this could happen is if NULL were passed as the "driver" name and virStrdup() returned 0. Since the calling functions check < 0 on the initial function call, the 0 possibility causes Coverity to complain. To fix this - enforce that the second parameter is not NULL using ATTRIBUTE_NONNULL(2) for the function prototype, then in virPCIDeviceDetach add an sa_assert(dev->stubDriver). This will result in Coverity not complaining any more.

util: two new pci util functions pciDeviceGetVirtualFunctionInfo returns pf netdevice name and virtual function index for a given vf. This is just a wrapper around existing functions to return vf's pf and vf_index with one api call pciConfigAddressToSysfsfile returns the sysfile pci device link from a 'struct pci_config_address' Signed-off-by: Roopa Prabhu <roprabhu@cisco.com>

ATTRIBUTE_RETURN_CHECK;
Use unsigned int instead of unsigned Though they are the same thing, mixed use of them is uncomfortable. "unsigned" is used a lot in old codes, this just tries to change the ones in utils.

char **pciConfigAddr)
Added Function virNetDevGetVirtualFunctions This functions enables us to get the Virtual Functions attached to a Physical function given the name of a SR-IOV physical functio. In order to accomplish the task, added a getter function pciGetDeviceAddrString to get the BDF of the Virtual Function in a char array.

pci: rename virPCIParseDeviceAddress and make it public This function has utility outside of virpci.c, so make it public. Also the name didn't fit convention, so change it to virPCIDeviceAddressParse.
