+ ---help---
+ A driver for 802.11b wireless cards based on the "Hermes" or
+ Intersil HFA384x (Prism 2) MAC controller. This includes the vast
+ majority of the PCMCIA 802.11b cards (which are nearly all rebadges)
+ - except for the Cisco/Aironet cards. Cards supported include the
+ Apple Airport (not a PCMCIA card), WavelanIEEE/Orinoco,
+ Cabletron/EnteraSys Roamabout, ELSA AirLancer, MELCO Buffalo, Avaya,
+ IBM High Rate Wireless, Farralon Syyline, Samsung MagicLAN, Netgear
+ MA401, LinkSys WPC-11, D-Link DWL-650, 3Com AirConnect, Intel
+ IPW2011, and Symbol Spectrum24 High Rate amongst others.
+
+ This option includes the guts of the driver, but in order to
+ actually use a card you will also need to enable support for PCMCIA
+ Hermes cards, PLX9052 based PCI adaptors or the Apple Airport below.
+
+ You will also very likely also need the Wireless Tools in order to
+ configure your card and that /etc/pcmcia/wireless.opts works :
+ <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>

+ depends on HERMES
+ ---help---
+
+ Say Y to enable support for Prism 2 and 2.5 chipsets. These
+ chipsets are better handled by the hostap driver. This driver
+ would not support WPA or firmware download for Prism chipset.
+
+ If you are not sure, say N.
+
+config HERMES_CACHE_FW_ON_INIT
+ bool "Cache Hermes firmware on driver initialisation"
+ depends on HERMES
+ default y
+ ---help---
+ Say Y to cache any firmware required by the Hermes drivers
+ on startup. The firmware will remain cached until the
+ driver is unloaded. The cache uses 64K of RAM.
+
+ Otherwise load the firmware from userspace as required. In
+ this case the driver should be unloaded and restarted
+ whenever the firmware is changed.
+
+ If you are not sure, say Y.
+
+config APPLE_AIRPORT
+ tristate "Apple Airport support (built-in)"
+ depends on PPC_PMAC && HERMES
+ help
+ Say Y here to support the Airport 802.11b wireless Ethernet hardware
+ built into the Macintosh iBook and other recent PowerPC-based
+ Macintosh machines. This is essentially a Lucent Orinoco card with
+ a non-standard interface.
+
+ This driver does not support the Airport Extreme (802.11b/g). Use
+ the BCM43xx driver for Airport Extreme cards.
+
+config PLX_HERMES

+ depends on PCI && HERMES
+ help
+ Enable support for PCMCIA cards supported by the "Hermes" (aka
+ orinoco) driver when used in PLX9052 based PCI adaptors. These
+ adaptors are not a full PCMCIA controller but act as a more limited
+ PCI <-> PCMCIA bridge. Several vendors sell such adaptors so that
+ 802.11b PCMCIA cards can be used in desktop machines. The Netgear
+ MA301 is such an adaptor.
+
+config TMD_HERMES
+ tristate "Hermes in TMD7160 based PCI adaptor support"

+

+ Enable support for PCI and mini-PCI 802.11b wireless NICs based on
+ the Prism 2.5 chipset. These are true PCI cards, not the 802.11b
+ PCMCIA cards bundled with PCI<->PCMCIA adaptors which are also
+ common. Some of the built-in wireless adaptors in laptops are of
+ this variety.
+
+config PCMCIA_HERMES

+ as the Lucent WavelanIEEE/Orinoco cards and their OEM (Cabletron/
+ EnteraSys RoamAbout 802.11, ELSA Airlancer, Melco Buffalo and
+ others). It should also be usable on various Prism II based cards
+ such as the Linksys, D-Link and Farallon Skyline. It should also
+ work on Symbol cards such as the 3Com AirConnect and Ericsson WLAN.
+
+ You will very likely need the Wireless Tools in order to
+ configure your card and that /etc/pcmcia/wireless.opts works:
+ <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
+

+ tristate "Symbol Spectrum24 Trilogy PCMCIA card support"
+ depends on PCMCIA && HERMES && HAS_IOPORT_MAP
+ ---help---

+ firmware, such as Symbol Wireless Networker LA4100, CompactFlash
+ cards by Socket Communications and Intel PRO/Wireless 2011B.
+

+/* Locking and synchronization:
+ *
+ * The basic principle is that everything is serialized through a
+ * single spinlock, priv->lock. The lock is used in user, bh and irq
+ * context, so when taken outside hardirq context it should always be
+ * taken with interrupts disabled. The lock protects both the
+ * hardware and the struct orinoco_private.
+ *
+ * Another flag, priv->hw_unavailable indicates that the hardware is
+ * unavailable for an extended period of time (e.g. suspended, or in
+ * the middle of a hard reset). This flag is protected by the
+ * spinlock. All code which touches the hardware should check the
+ * flag after taking the lock, and if it is set, give up on whatever
+ * they are doing and drop the lock again. The orinoco_lock()
+ * function handles this (it unlocks and returns -EBUSY if
+ * hw_unavailable is non-zero).

+ *
+ * Here's the general details on how the PLX9052 adapter works:
+ *
+ * - Two PCI I/O address spaces, one 0x80 long which contains the
+ * PLX9052 registers, and one that's 0x40 long mapped to the PCMCIA
+ * slot I/O address space.
+ *
+ * - One PCI memory address space, mapped to the PCMCIA attribute space
+ * (containing the CIS).
+ *
+ * Using the later, you can read through the CIS data to make sure the
+ * card is compatible with the driver. Keep in mind that the PCMCIA
+ * spec specifies the CIS as the lower 8 bits of each word read from
+ * the CIS, so to read the bytes of the CIS, read every other byte
+ * (0,2,4,...). Passing that test, you need to enable the I/O address
+ * space on the PCMCIA card via the PCMCIA COR register. This is the
+ * first byte following the CIS. In my case (which may not have any
+ * relation to what's on the PRISM2 cards), COR was at offset 0x800
+ * within the PCI memory space. Write 0x41 to the COR register to
+ * enable I/O mode and to select level triggered interrupts. To
+ * confirm you actually succeeded, read the COR register back and make
+ * sure it actually got set to 0x41, in case you have an unexpected
+ * card inserted.
+ *
+ * Following that, you can treat the second PCI I/O address space (the
+ * one that's not 0x80 in length) as the PCMCIA I/O space.
+ *
+ * Note that in the Eumitcom's source for their drivers, they register
+ * the interrupt as edge triggered when registering it with the
+ * Windows kernel. I don't recall how to register edge triggered on
+ * Linux (if it can be done at all). But in some experimentation, I
+ * don't see much operational difference between using either
+ * interrupt mode. Don't mess with the interrupt mode in the COR
+ * register though, as the PLX9052 wants level triggers with the way
+ * the serial EEPROM configures it on the WL11000.
+ *
+ * There's some other little quirks related to timing that I bumped
+ * into, but I don't recall right now. Also, there's two variants of
+ * the WL11000 I've seen, revision A1 and T2. These seem to differ
+ * slightly in the timings configured in the wait-state generator in
+ * the PLX9052. There have also been some comments from Eumitcom that
+ * cards shouldn't be hot swapped, apparently due to risk of cooking
+ * the PLX9052. I'm unsure why they believe this, as I can't see
+ * anything in the design that would really cause a problem, except
+ * for crashing drivers not written to expect it. And having developed
+ * drivers for the WL11000, I'd say it's quite tricky to write code
+ * that will successfully deal with a hot unplug. Very odd things
+ * happen on the I/O side of things. But anyway, be warned. Despite
+ * that, I've hot-swapped a number of times during debugging and
+ * driver development for various reasons (stuck WAIT# line after the
+ * radio card's firmware locks up).

- ---help---
- A driver for 802.11b wireless cards based on the "Hermes" or
- Intersil HFA384x (Prism 2) MAC controller. This includes the vast
- majority of the PCMCIA 802.11b cards (which are nearly all rebadges)
- - except for the Cisco/Aironet cards. Cards supported include the
- Apple Airport (not a PCMCIA card), WavelanIEEE/Orinoco,
- Cabletron/EnteraSys Roamabout, ELSA AirLancer, MELCO Buffalo, Avaya,
- IBM High Rate Wireless, Farralon Syyline, Samsung MagicLAN, Netgear
- MA401, LinkSys WPC-11, D-Link DWL-650, 3Com AirConnect, Intel
- IPW2011, and Symbol Spectrum24 High Rate amongst others.
-
- This option includes the guts of the driver, but in order to
- actually use a card you will also need to enable support for PCMCIA
- Hermes cards, PLX9052 based PCI adaptors or the Apple Airport below.
-
- You will also very likely also need the Wireless Tools in order to
- configure your card and that /etc/pcmcia/wireless.opts works :

- would not support WPA or firmware download for Prism chipset.
-
- If you are not sure, say N.

- bool "Cache Hermes firmware on driver initialisation"
- depends on HERMES
- default y
- ---help---
- Say Y to cache any firmware required by the Hermes drivers
- on startup. The firmware will remain cached until the
- driver is unloaded. The cache uses 64K of RAM.
-

- PCI <-> PCMCIA bridge. Several vendors sell such adaptors so that
- 802.11b PCMCIA cards can be used in desktop machines. The Netgear

-/* Locking and synchronization:
- *
- * The basic principle is that everything is serialized through a
- * single spinlock, priv->lock. The lock is used in user, bh and irq
- * context, so when taken outside hardirq context it should always be
- * taken with interrupts disabled. The lock protects both the
- * hardware and the struct orinoco_private.
- *
- * Another flag, priv->hw_unavailable indicates that the hardware is
- * unavailable for an extended period of time (e.g. suspended, or in
- * the middle of a hard reset). This flag is protected by the
- * spinlock. All code which touches the hardware should check the
- * flag after taking the lock, and if it is set, give up on whatever
- * they are doing and drop the lock again. The orinoco_lock()
- * function handles this (it unlocks and returns -EBUSY if
- * hw_unavailable is non-zero).

- *
- * Here's the general details on how the PLX9052 adapter works:
- *
- * - Two PCI I/O address spaces, one 0x80 long which contains the
- * PLX9052 registers, and one that's 0x40 long mapped to the PCMCIA
- * slot I/O address space.
- *
- * - One PCI memory address space, mapped to the PCMCIA attribute space
- * (containing the CIS).
- *
- * Using the later, you can read through the CIS data to make sure the
- * card is compatible with the driver. Keep in mind that the PCMCIA
- * spec specifies the CIS as the lower 8 bits of each word read from
- * the CIS, so to read the bytes of the CIS, read every other byte
- * (0,2,4,...). Passing that test, you need to enable the I/O address
- * space on the PCMCIA card via the PCMCIA COR register. This is the
- * first byte following the CIS. In my case (which may not have any
- * relation to what's on the PRISM2 cards), COR was at offset 0x800
- * within the PCI memory space. Write 0x41 to the COR register to
- * enable I/O mode and to select level triggered interrupts. To
- * confirm you actually succeeded, read the COR register back and make
- * sure it actually got set to 0x41, in case you have an unexpected
- * card inserted.
- *
- * Following that, you can treat the second PCI I/O address space (the
- * one that's not 0x80 in length) as the PCMCIA I/O space.
- *
- * Note that in the Eumitcom's source for their drivers, they register
- * the interrupt as edge triggered when registering it with the
- * Windows kernel. I don't recall how to register edge triggered on
- * Linux (if it can be done at all). But in some experimentation, I
- * don't see much operational difference between using either
- * interrupt mode. Don't mess with the interrupt mode in the COR
- * register though, as the PLX9052 wants level triggers with the way
- * the serial EEPROM configures it on the WL11000.
- *
- * There's some other little quirks related to timing that I bumped
- * into, but I don't recall right now. Also, there's two variants of
- * the WL11000 I've seen, revision A1 and T2. These seem to differ
- * slightly in the timings configured in the wait-state generator in
- * the PLX9052. There have also been some comments from Eumitcom that
- * cards shouldn't be hot swapped, apparently due to risk of cooking
- * the PLX9052. I'm unsure why they believe this, as I can't see
- * anything in the design that would really cause a problem, except
- * for crashing drivers not written to expect it. And having developed
- * drivers for the WL11000, I'd say it's quite tricky to write code
- * that will successfully deal with a hot unplug. Very odd things
- * happen on the I/O side of things. But anyway, be warned. Despite
- * that, I've hot-swapped a number of times during debugging and
- * driver development for various reasons (stuck WAIT# line after the
- * radio card's firmware locks up).
