+config HERMES
+ tristate "Hermes chipset 802.11b support (Orinoco/Prism2/Symbol)"
+ depends on (PPC_PMAC || PCI || PCMCIA) && WLAN_80211
+ select WIRELESS_EXT
+ select FW_LOADER
+ select CRYPTO
+ select CRYPTO_MICHAEL_MIC
+ ---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>
+
+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
+ tristate "Hermes in PLX9052 based PCI adaptor support (Netgear MA301 etc.)"
+ 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"
+ depends on PCI && HERMES
+ help
+ Enable support for PCMCIA cards supported by the "Hermes" (aka
+ orinoco) driver when used in TMD7160 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.

+ help
+ Enable support for PCMCIA cards supported by the "Hermes" (aka
+ orinoco) driver when used in Nortel emobility PCI adaptors. These
+ adaptors are not full PCMCIA controllers, but act as a more limited
+ PCI <-> PCMCIA bridge.
+
+config PCI_HERMES
+ tristate "Prism 2.5 PCI 802.11b adaptor support"
+ depends on PCI && HERMES
+ help
+ 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
+ tristate "Hermes PCMCIA card support"
+ depends on PCMCIA && HERMES
+ ---help---
+ A driver for "Hermes" chipset based PCMCIA wireless adaptors, such
+ 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>.
+
+config PCMCIA_SPECTRUM
+ tristate "Symbol Spectrum24 Trilogy PCMCIA card support"
+ depends on PCMCIA && HERMES
+ ---help---
+
+ This is a driver for 802.11b cards using RAM-loadable Symbol
+ firmware, such as Symbol Wireless Networker LA4100, CompactFlash
+ cards by Socket Communications and Intel PRO/Wireless 2011B.
+
+ This driver requires firmware download on startup. Utilities
+ for downloading Symbol firmware are available at
+ <http://sourceforge.net/projects/orinoco/>

+/* 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).

-/* 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).
