- ---help---
- Shared driver code for IEEE 802.11b wireless cards based on
- Intersil Prism2/2.5/3 chipset. This driver supports so called
- Host AP mode that allows the card to act as an IEEE 802.11
- access point.
-
- 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
- PLX/PCI/CS version of the driver to actually use the driver.
-
- The driver can be compiled as a module and it will be called
- hostap.
-
-config HOSTAP_FIRMWARE
- bool "Support downloading firmware images with Host AP driver"
- depends on HOSTAP
- ---help---
- Configure Host AP driver to include support for firmware image
- download. This option by itself only enables downloading to the
- volatile memory, i.e. the card RAM. This option is required to
- support cards that don't have firmware in flash, such as D-Link
- DWL-520 rev E and D-Link DWL-650 rev P.
-
- Firmware image downloading needs a user space tool, prism2_srec.
- It is available from http://hostap.epitest.fi/.
-
-config HOSTAP_FIRMWARE_NVRAM
- bool "Support for non-volatile firmware download"
- depends on HOSTAP_FIRMWARE
- ---help---
- Allow Host AP driver to write firmware images to the non-volatile
- card memory, i.e. flash memory that survives power cycling.
- Enable this option if you want to be able to change card firmware
- permanently.
-
- Firmware image downloading needs a user space tool, prism2_srec.
- It is available from http://hostap.epitest.fi/.

- * tx_errors/tx_dropped are added to the main netdevice; using sw_support

- * 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

+ *
+ * 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.
