Remove Host AP driver FAQ from the git repository
There is no need to keep this in hostap.git with wpa_supplicant and hostapd. The CVS version from 0.5.x branch is identical and it can be used instead.

-===========================================
-
-1. What does "GetNextTuple: No more items" mean in hostap_cs initialization?
-2. Why RX does not work?

-4. What is causing 'Unresolved symbols' in depmod/modprobe?
-5. How can I upgrade Prism2/2.5/3 firmware?
-6. Why did I get two network interfaces (wlan0 and wifi0) even when I have
- only one wireless card?
-7. Why does my D-Link DWL-650 rev. P1 or D-Link DWL-520 rev. E1 (or any other
- card with small flash) card fail?
-8. Does Host AP driver support IEEE 802.11a and 802.11g? Does it support

-
-
-
-1. What does "GetNextTuple: No more items" mean in hostap_cs initialization?
-
-This is one of the most often reported problems in getting the
-hostap_cs.o driver working. It is usually reported for D-Link DWL-650
-PC Card, e.g., on ISA-to-PCMCIA adapter. Later versions of the driver
-report this also with "Vcc mismatch - skipping this entry".
-
-Most common reason for getting this is a mismatch in voltage
-configuration. The driver tries to make sure that the voltage (Vcc)
-configuration in CIS and the slot match each other. It refuses to
-initialize the card if the card CIS does not include a CFTABLE entry
-with a matching Vcc value. This seems to be a problem for some cases
-since the CIS is invalid or the reported voltage is incorrect.
-
-As a workaround, the driver supports a module parameter ignore_cis_vcc
-that can be used to skip this verification. This can be enabled by
-setting ignore_cis_vcc=1 in /etc/pcmcia/hostap_cs.conf (commented
-example line in the end of file). This can also be tested by manually
-loading the module with 'modprobe hostap_cs ignore_cis_vcc=1' before
-inserting the card).
-
-
-
-2. Why RX does not work?
- What does "NETDEV WATCHDOG: wlan0: transmit timed out" mean?
- (interrupt delivery problems)
-
-If the driver does not seem to receive any packets or sending packets
-results in "NETDEV WATCHDOG: wlan0: transmit timed out", the reason is
-probably in interrupt delivery problems. This is quite common with
-PCI-to-PCMCIA adapters. Newer than 2002-05-19 of the driver have a
-test that will report this after the initialization ("wlan: Possible
-interrupt delivery problem"). Another method for checking this is to
-observer whether interrupt counters in /proc/interrupts increase for
-hostap_cs/wlan0 entry.
-
-Adding suitable irq_mode=# setting in PCIC_OPTS line of
-pcmcia-configuration is the most common fix for this. pcmcia-cs HOWTO
-has more information on how to debug and fix interrupt delivery
-problems at
-http://pcmcia-cs.sourceforge.net/ftp/doc/PCMCIA-HOWTO-5.html#irqmode
-
-
-
-3. What is wrong with Host AP mode in secondary (station) firmware v1.4.2?
-
-It looks like secondary firmware v1.4.2 sends beacon frames properly,
-but does not respond to probe requests. With most station cards, this
-prevents authentication and association and thus, in practice, no data
-frames can be sent. It has been reported that at least some Cisco
-Aironet 350 cards can associate with Host AP mode even with firmware
-v1.4.2 (i.e., without receiving probe response), but Prism2 and
-Lucent/ORiNOCO/Agere seem to require probe response and they do not
-thus associate with AP using v1.4.2 firmware.
-
-This is fixed in later secondary firmware versions; probably already
-in 1.4.3, but at least 1.4.9 has been tested to work. In other words,
-this problem can be fixed by upgrading card firmware.
-
-
-
-4. What is causing 'Unresolved symbols' in depmod/modprobe?
-
-Installation of Host AP driver (e.g, 'make install_pccard') may report
-unresolved symbols when running depmod. These are usually caused with
-mismatch in kernel configuration for modversions.
-
-Example:
-
-depmod reports unresolved symbol 'eth_type_trans' (this is without
-modversions):
-depmod: eth_type_trans
-
-but kernel was really configured with CONFIG_MODVERSIONS:
-
-# grep eth_type_trans /proc/ksyms
-c01b66c0 eth_type_trans_Rdb9cd26f
-
-(notice the _R... postfix)
-
-This happens if the kernel configuration given to Host AP driver's
-Makefile (.config in KERNEL_PATH) has not CONFIG_MODVERSIONS, but the
-running kernel is compiled with it.
-If the kernel were configured without modversions, /proc/ksyms would
-show the symbols with _R... postfix:
-
-
-Mismatches in kernel configuration can be fixed by using the same
-configuration (i.e., Linux kernel .config) for both the kernel and the
-driver. If you are using a kernel from a distribution installation
-(i.e., you have not compiled it yourself), you will need to create a
-matching .config file somehow. This depends on the distribution you
-are using, but 'make oldconfig' in kernel source directory might work
-with some distributions. If you compile the kernel yourself, it will
-be easier, since you already have to have created the correct .config
-file.

-
-5. How can I upgrade Prism2/2.5/3 firmware?
-
-Prism2/2.5/3 cards and Host AP driver support two different mechanism
-of upgrading the card firmware. Firmware images (primary and station)
-can be downloaded either into volatile memory (RAM download) or
-non-volatile memory (flash upgrade). Firmware images downloaded into
-volatile memory are lost when the card is resetted, so they are quite
-safe. Flash upgrade with incorrect images may cause permanent problems
-(i.e., render the card useless), so certain amount of caution is
-always recommended for this.
-
-Note! Some of the older versions of Host AP driver or prism2_srec had
-fatal bugs in flash upgrade. Only versions 0.1.0 or newer should be
-used when performing non-volatile flash upgrade!
-
-utils/prism2_srec (run 'make' in utils directory to build this) is a
-tool that can be instructed Host AP driver to download firmware image
-into the wlan card. Brief usage information is available by running
-this program without any command line parameters. Please note, that
-the downloading support is disabled in the default Host AP driver
-build. You will need to change this by defining
-PRISM2_DOWNLOAD_SUPPORT (and PRISM2_NON_VOLATILE_DOWNLOAD if you want
-to update flash); see driver/modules/hostap_config.h for more details.

-Chipsets. This is available at http://linux.junsun.net/intersil-prism/.
-
-
-
-6. Why did I get two network interfaces (wlan0 and wifi0) even when I have
- only one wireless card?
-
-Host AP driver supports multiple virtual interfaces per wireless
-card. wifi0 is the master radio interface and wlan0 is the first
-virtual interface for this radio. Other virtual interfaces are wlan0ap
-(for hostapd), and one interface per WDS link.
-
-In most cases, one should ignore wifi0 interface and just use wlan0
-interface. In other words, assign IP address to wlan0, not wifi0 and
-in general, just ignore the wifi0 interface.
-
-
-
-7. Why does my D-Link DWL-650 rev. P1 or D-Link DWL-520 rev. E1 (or any other
- card with small flash) card fail?
-
-Some of the new Prism3-based cards use a smaller flash chip that does
-not include full firmware for the card. For example, D-Link DWL-650
-rev. P1 and D-Link DWL-520 rev. E1 are such cards. These cards require
-that the firmware is downloaded to the card during initialization. See
-utils/hostap_fw_load for example commands on doing this.
-
-
-
-8. Does Host AP driver support IEEE 802.11a and 802.11g? Does it support
- chipsets other than Prism 2/2.5/3?
-
-Host AP driver supports only Intersil Prism chipsets, versions 2, 2.5,
-and 3. Those chipsets support IEEE 802.11b only; other chipsets are
-not supported. All utilities distributed with Host AP driver except
-wpa_supplicant work only with Host AP driver, so they are limited to
-the same hardware. wpa_supplicant works with other drivers, including
-those that support 802.11a and 802.11g.
