Currently ivshmem device can only be configurated as single function device(bdf.f = 0) on bus 0. This greatly limits the number of ivshmem devices we can create. This patch is to enable multiple function bit in HEADER_TYPE config register, so that we can create many more ivshmem devices by using different function numbers on one bus:dev. The multi function device bit is to be set on ivshmem devices whose function number equls 0. PCI spec describe it as: ‘When Set, indicates that the Device may contain multiple Functions, but not necessarily.’, So if this dev is the only one on the bus:dev, it is still OK.
