+Description:
+ If the permissive attribute is set, then writing a string in
+ the format of DDDD:BB:DD.F-REG:SIZE:MASK will allow the guest
+ to write and read from the PCI device. That is Domain:Bus:
+ Device.Function-Register:Size:Mask (Domain is optional).
+ For example:
+ #echo 00:19.0-E0:2:FF > /sys/bus/pci/drivers/pciback/quirks
+ will allow the guest to read and write to the configuration
+ register 0x0E.

+Description:
+ A list of all of the PCI devices owned by Xen PCI back and
+ whether Xen PCI backend will acknowledge the interrupts received
+ and the amount of interrupts received. Xen PCI back acknowledges
+ said interrupts only when they are level, shared with another
+ guest, and enabled by the guest.
