23 * Atheros Hardware Access Layer
25 * Clients of the HAL call ath_hal_attach to obtain a reference to an ath_hal
26 * structure for use with the device. Hardware-related operations that
27 * follow must call back into the HAL through interface, supplying the
28 * reference as the first parameter.
34 * The maximum number of TX/RX chains supported.
35 * This is intended to be used by various statistics gathering operations
38 #define AH_MAX_CHAINS 3
39 #define AH_MIMO_MAX_EVM_PILOTS 6
42 * __ahdecl is analogous to _cdecl; it defines the calling
43 * convention used within the HAL. For most systems this
44 * can just default to be empty and the compiler will (should)
45 * use _cdecl. For systems where _cdecl is not compatible this
46 * must be defined. See linux/ah_osdep.h for an example.
53 * Status codes that may be returned by the HAL. Note that
54 * interfaces that return a status code set it only when an
55 * error occurs--i.e. you cannot check it for success.
