EAL -a and -b options are used to specify which PCI devices are explicitly allowed or blocked during PCI bus scan. This evaluation is missing in the Windows implementation of rte_pci_scan. This patch provides this missing functionality, so that apps can specify which NetUIO devices to ignore during PCI bus scan.
