23 Abstract: Data structures for the rt2x00pci module.
24 Supported chipsets: rt2460, rt2560, rt2561, rt2561s & rt2661.
31 * This variable should be used with the
32 * pci_driver structure initialization.
34 #define PCI_DEVICE_DATA(__ops) .driver_data = (kernel_ulong_t)(__ops)
38 * When register access attempts should be repeated
39 * only REGISTER_BUSY_COUNT attempts with a delay
40 * of REGISTER_BUSY_DELAY us should be taken.
42 #define REGISTER_BUSY_COUNT 5
43 #define REGISTER_BUSY_DELAY 100
46 * Descriptor availability flags.
47 * All PCI device descriptors have these 2 flags
48 * with the exact same definition.
