+.Sh NAME
+.Nm ath
+.Nd Atheros IEEE 802.11 driver
+.Sh SYNOPSIS
+.Cd "ath* at pci? dev ? function ?"
+.Cd "ath* at cardbus? function ?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for wireless network adapters based on
+the Atheros AR2413, AR2417, AR5210, AR5211, AR5212, AR5213, AR5413,
+AR5416, AR5424, AR9160, AR9280, and AR9285 chips.
+Chip-specific support is provided by the Atheros Hardware Access Layer
+(HAL).
+.Pp
+Supported features include 802.11 and 802.3 frames, power management, BSS,
+IBSS, and host-based access point operation modes.
+All host/device interaction is via DMA.
+.Pp
+The
+.Nm
+driver encapsulates all IP and ARP traffic as 802.11 frames, however
+it can receive either 802.11 or 802.3 frames.
+Transmit speed and operating mode is selectable
+depending on your hardware.
+.Pp
+AR5210-based devices support 802.11a operation with transmit speeds
+of 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps, 24 Mbps, 36 Mbps, 48 Mbps, and 54 Mbps.
+.Pp
+AR5211-based devices support 802.11a and 802.11b operation with transmit
+speeds as above for 802.11a operation and
+1Mbps, 2Mbps, 5.5 Mbps and 11Mbps for 802.11b operation.
+.Pp
+AR5212-based and AR5213-based devices support 802.11a, 802.11b, and
+802.11g operation with transmit speeds appropriate to each.
+.Pp
+All chips also support an Atheros Turbo Mode (TM) that operates in the
+802.11a frequency range with 2x the transmit speeds.
+(This mode is, however, only interoperable with other Atheros-based devices.)
+.Pp
+The actual transmit speed used is dependent on signal quality and the
+.Dq rate control
+algorithm employed by the driver.
+All chips support WEP encryption.
+.Pp
+By default, the
+.Nm
+driver configures the card for BSS operation (aka infrastructure
+mode).
+This mode requires the use of an access point (base station).
+.Pp
+The
+.Nm
+driver also supports the standard IBSS point-to-point mode
+where stations can communicate amongst themselves without the
+aid of an access point.
+.Pp
+The driver may also be configured to operate in hostap mode.
+In this mode a host may function as an access point (base station).
+Access points are different than operating in IBSS mode.
+They operate in BSS mode.
+They allow for easier roaming and bridge all Ethernet traffic such
+that machines connected via an access point appear to be on the local
+Ethernet segment.
+.Pp
+The mode of operation is chosen by specifying the appropriate mediaopt
+value to ifconfig.
+The
+.Fl m
+flag to ifconfig will list the available options.
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Pp
+Devices supported by the
+.Nm
+driver come in either CardBus or mini-PCI packages.
+Wireless cards in CardBus slots may be inserted and ejected on the fly.
+.Pp
+The following cards are among those supported by the
+.Nm
+driver:

+.Sh DIAGNOSTICS
+.Bl -diag
+.It "ath%d: unable to attach hardware; HAL status %u"
+The Atheros Hardware Access Layer was unable to configure the hardware
+as requested.
+The status code is explained in the HAL include file
+.Pa contrib/sys/dev/ic/athhal.h .
+.It "ath%d: failed to allocate descriptors: %d"
+The driver was unable to allocate contiguous memory for the transmit
+and receive descriptors.
+This usually indicates system memory is scarce and/or fragmented.
+.It "ath%d: unable to setup a data xmit queue!"
+The request to the HAL to setup the transmit queue for normal
+data frames failed.
+This should not happen.
+.It "ath%d: unable to setup a beacon xmit queue!"
+The request to the HAL to setup the transmit queue for 802.11 beacon frames
+failed.
+This should not happen.
+.It "ath%d: 802.11 address: %s"
+The MAC address programmed in the EEPROM is displayed.
+.It "ath%d: hardware error; resetting"
+An unrecoverable error in the hardware occurred.
+Errors of this sort include unrecoverable DMA errors.
+The driver will reset the hardware and continue.
+.It "ath%d: rx FIFO overrun; resetting"
+The receive FIFO in the hardware overflowed before the data could be
+transferred to the host.
+This typically occurs because the hardware ran short of receive
+descriptors and had no place to transfer received data.
+The driver will reset the hardware and continue.
+.It "ath%d: unable to reset hardware; hal status %u"
+The Atheros Hardware Access Layer was unable to reset the hardware
+as requested.
+The status code is explained in the HAL include file
+.Pa sys/external/isc/atheros_hal/dist/ah.h .
+This should not happen.
+.It "ath%d: unable to start recv logic"
+The driver was unable to restart frame reception.
+This should not happen.
+.It "ath%d: device timeout"
+A frame dispatched to the hardware for transmission did not complete in time.
+The driver will reset the hardware and continue.
+This should not happen.
+.It "ath%d: bogus xmit rate 0x%x"
+An invalid transmit rate was specified for an outgoing frame.
+The frame is discarded.
+This should not happen.
+.It "ath%d: ath_chan_set: unable to reset channel %u (%u MHz)"
+The Atheros Hardware Access Layer was unable to reset the hardware
+when switching channels during scanning.
+This should not happen.
+.It "ath%d: unable to allocate channel table"
+The driver was unable to allocate memory for the table used to hold
+the set of available channels.
+.It "ath%d: unable to collect channel list from hal"
+A problem occurred while querying the HAL to find the set of available
+channels for the device.
+This should not happen.
+.It "ath%d: %s: %dM -> %dM (%d ok, %d err, %d retr)"
+The driver's rate control algorithm changed the current rate for transmitting
+frames.
+This message is temporarily enabled for normal use to help in diagnosing
+and improving the rate control algorithm.
+The message indicates the new and old transmit rates and the statistics
+it used to decide on this change.
+.It "ath%d: failed to enable memory mapping"
+The driver was unable to enable memory-mapped I/O to the PCI device registers.
+This should not happen.
+.It "ath%d: failed to enable bus mastering"
+The driver was unable to enable the device as a PCI bus master for doing DMA.
+This should not happen.
+.It "ath%d: cannot map register space"
+The driver was unable to map the device registers into the host address space.
+This should not happen.
+.It "ath%d: could not map interrupt"
+The driver was unable to allocate an IRQ for the device interrupt.
+This should not happen.
+.It "ath%d: could not establish interrupt"
+The driver was unable to install the device interrupt handler.
+This should not happen.

+device driver first appeared in

+.Sh CAVEATS
+Different regulatory domains have different default channels for adhoc
+mode.
+See
+.Xr ifconfig 8
+for information on how to change the channel.
+Different regulatory domains may not be able to communicate with each
+other with 802.11a as different regulatory domains do not necessarily
+have overlapping channels.
+.Pp
+Revision A1 of the D-LINK DWL-G520 and DWL-G650 are based on an
+Intersil PrismGT chip and are not supported by this driver.
+.Pp
+Revision v2 of the Netgear WG311 is based on a Texas Instruments ACX111
+and is not supported by this driver.
+.Pp
+Revision v3 of the Netgear WG311 is based on a Marvell Libertas
+88W8335 and is not supported by this driver.
+.Sh BUGS
+Performance in lossy environments is suboptimal.
+The algorithm used to select the rate for transmitted packets is
+very simplistic.
+There is no software retransmit; only hardware retransmit is used.
+Contributors are encouraged to replace the existing rate control algorithm
+with a better one (hint: all the information needed is available to the driver).
+.Pp
+The driver does not fully enable power-save operation of the chip;
+consequently power use is suboptimal.
