Sys files of 'extended_tag' and 'max_read_request_size' have been supported in igb_uio, and can be changed during probing PCI. Three items in configuration files are needed to support them at compile time. Those three items are, - CONFIG_RTE_PCI_CONFIG - CONFIG_RTE_PCI_EXTENDED_TAG - CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE
