22 Module: rt2x00pci
23 Abstract: Data structures for the rt2x00pci module.
26 #ifndef RT2X00PCI_H
27 #define RT2X00PCI_H
29 #include <linux/io.h>
32 * This variable should be used with the
33 * pci_driver structure initialization.
35 #define PCI_DEVICE_DATA(__ops) .driver_data = (kernel_ulong_t)(__ops)
38 * Register defines.
39 * Some registers require multiple attempts before success,
40 * in those cases REGISTER_BUSY_COUNT attempts should be
41 * taken with a REGISTER_BUSY_DELAY interval.
43 #define REGISTER_BUSY_COUNT 5
44 #define REGISTER_BUSY_DELAY 100
47 * Descriptor availability flags.
48 * All PCI device descriptors have these 2 flags
49 * with the exact same definition.
50 * By storing them here we can use them inside rt2x00pci
51 * for some simple entry availability checking.

55 #define RXD_ENTRY_OWNER_NIC FIELD32(0x00000001)
58 * Register access.
