+	help
+	  If you have a wireless card belonging to this class, say Y.
+
+	  Note that the answer to this question doesn't directly affect the
+	  kernel: saying N will just cause the configurator to skip all the
+	  questions about these cards. If you say Y, you will be asked for
+	  your specific card in the following questions.

+	  This enables support for FullMAC PCI/Cardbus prism54 devices. This
+	  driver is now deprecated in favor for the SoftMAC driver, p54pci.
+	  p54pci supports FullMAC PCI/Cardbus devices as well.
+
+	  For more information refer to the p54 wiki:
+
+	  http://wireless.wiki.kernel.org/en/users/Drivers/p54
+
+	  Note: You need a motherboard with DMA support to use any of these cards
+
+	  When built as module you get the module prism54

+	Shared driver code for IEEE 802.11b wireless cards based on

+	Host AP mode that allows the card to act as an IEEE 802.11

+	See <http://hostap.epitest.fi/> for more information about the
+	Host AP driver configuration and tools. This site includes
+	information and tools (hostapd and wpa_supplicant) for WPA/WPA2
+	support.
+
+	This option includes the base Host AP driver code that is shared by
+	different hardware models. You will also need to enable support for

+	DWL-520 rev E and D-Link DWL-650 rev P.
+
+	Firmware image downloading needs a user space tool, prism2_srec.

+ * FIX:
+ * - there is currently no way of associating TX packets to correct wds device
+ *   when TX Exc/OK event occurs, so all tx_packets and some
+ *   tx_errors/tx_dropped are added to the main netdevice; using sw_support
+ *   field in txdesc might be used to fix this (using Alloc event to increment
+ *   tx_packets would need some further info in txfid table)
+ *
+ * Buffer Access Path (BAP) usage:
+ *   Prism2 cards have two separate BAPs for accessing the card memory. These
+ *   should allow concurrent access to two different frames and the driver
+ *   previously used BAP0 for sending data and BAP1 for receiving data.
+ *   However, there seems to be number of issues with concurrent access and at
+ *   least one know hardware bug in using BAP0 and BAP1 concurrently with PCI
+ *   Prism2.5. Therefore, the driver now only uses BAP0 for moving data between
+ *   host and card memories. BAP0 accesses are protected with local->baplock
+ *   (spin_lock_bh) to prevent concurrent use.

+	  Apple Airport (not a PCMCIA card), WavelanIEEE/Orinoco,

+	  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 :

+/* hermes.c
+ *
+ * Driver core for the "Hermes" wireless MAC controller, as used in
+ * the Lucent Orinoco and Cabletron RoamAbout cards. It should also
+ * work on the hfa3841 and hfa3842 MAC controller chips used in the
+ * Prism II chipsets.
+ *
+ * This is not a complete driver, just low-level access routines for
+ * the MAC controller itself.
+ *
+ * Based on the prism2 driver from Absolute Value Systems' linux-wlan
+ * project, the Linux wvlan_cs driver, Lucent's HCF-Light
+ * (wvlan_hcf.c) library, and the NetBSD wireless driver (in no
+ * particular order).

+/* 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).

+ * 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.

+ *
+ * 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
