; PCI vendor and hardware types for hardware supported by the above drivers
; If you add a driver, ensure you update this datastructure, otherwise the
; card will not be probed.
; Each driver is defined by 4 double words. These are
;   PCIVendorDevice  probeFunction ResetFunction PollFunction transmitFunction
; The last entry must be kept at all zeros, to indicate the end of the list
; As a PCI driver may support more than one hardware implementation, there may
; be several lines which refer to the same functions.
; The first driver found on the PCI bus will be the one used.
