In typical fashion, getting documentation about this - * controller is about as easy as squeezing blood from a stone. Here - * is more or less what I know: - * - * - The Hermes controller is firmware driven, and the host interacts - * with the Hermes via a firmware interface, which can change. - * - * - The Hermes is described in a document called: "Hermes Firmware - * WaveLAN/IEEE Station Functions," document #010245, which of course - * Lucent will not release without an NDA. - * - * - Lucent has created a library called HCF (Hardware Control Functions) - * though which it wants developers to interact with the card. The HCF - * is needlessly complex, ill conceived and badly documented. Actually, - * the comments in the HCP code itself aren't bad, but the publically - * available manual that comes with it is awful, probably due largely to - * the fact that it has been emasculated in order to hide information - * that Lucent wants to keep proprietary. The purpose of the HCF seems - * to be to insulate the driver programmer from the Hermes itself so that - * Lucent has an excuse not to release programming in for it. - * - * - Lucent only makes available documentation and code for 'HCF Light' - * which is a stripped down version of HCF with certain features not - * implemented, most notably support for 802.11 frames. - * - * - The HCF code which I have seen blows goats. Whoever decided to - * use a 132 column format should be shot. - * - * Rather than actually use the Lucent HCF library, I have stripped all - * the useful information from it and used it to create a driver in the - * usual BSD form. Note: I don't want to hear anybody whining about the - * fact that the Lucent code is GPLed and mine isn't. I did not actually - * put any of Lucent's code in this driver: I only used it as a reference - * to obtain information about the underlying hardware. The Hermes - * programming interface is not GPLed, so bite me. - */ - -/* - * Size of Hermes I/O space. - */ -#define WI_IOSIZ 0x40 - -/* - * Hermes register definitions and what little I know about them. - */ - -/* Hermes command/status registers. */ -#define WI_COMMAND 0x00 -#define WI_PARAM0 0x02 -#define WI_PARAM1 0x04 -#define WI_PARAM2 0x06 -#define WI_STATUS 0x08 -#define WI_RESP0 0x0A -#define WI_RESP1 0x0C -#define WI_RESP2 0x0E - -/* Command register values. */ -#define WI_CMD_BUSY 0x8000 /* busy bit */ -#define WI_CMD_INI 0x0000 /* initialize */ -#define WI_CMD_ENABLE 0x0001 /* enable */ -#define WI_CMD_DISABLE 0x0002 /* disable */ -#define WI_CMD_DIAG 0x0003 -#define WI_CMD_ALLOC_MEM 0x000A /* allocate NIC memory */ -#define WI_CMD_TX 0x000B /* transmit */ -#define WI_CMD_NOTIFY 0x0010 -#define WI_CMD_INQUIRE 0x0011 -#define WI_CMD_ACCESS 0x0021 -#define WI_CMD_PROGRAM 0x0022 - -#define WI_CMD_CODE_MASK 0x003F - -/* - * Reclaim qualifier bit, applicable to the - * TX and INQUIRE commands. - */ -#define WI_RECLAIM 0x0100 /* reclaim NIC memory */ - -/* - * ACCESS command qualifier bits. - */ -#define WI_ACCESS_READ 0x0000 -#define WI_ACCESS_WRITE 0x0100 - -/* - * PROGRAM command qualifier bits. - */ -#define WI_PROGRAM_DISABLE 0x0000 -#define WI_PROGRAM_ENABLE_RAM 0x0100 -#define WI_PROGRAM_ENABLE_NVRAM 0x0200 -#define WI_PROGRAM_NVRAM 0x0300 - -/* Status register values */ -#define WI_STAT_CMD_CODE 0x003F -#define WI_STAT_DIAG_ERR 0x0100 -#define WI_STAT_INQ_ERR 0x0500 -#define WI_STAT_CMD_RESULT 0x7F00 - -/* memory handle management registers */ -#define WI_INFO_FID 0x10 -#define WI_RX_FID 0x20 -#define WI_ALLOC_FID 0x22 -#define WI_TX_CMP_FID 0x24 - -/* - * Buffer Access Path (BAP) registers. - * These are I/O channels.
