+config ATM_DUMMY
+	tristate "Dummy ATM driver"

+config ATM_LANAI
+	tristate "Efficient Networks Speedstream 3010"
+	depends on PCI && ATM
+	help
+	  Supports ATM cards based on the Efficient Networks "Lanai"
+	  chipset such as the Speedstream 3010 and the ENI-25p.  The
+	  Speedstream 3060 is currently not supported since we don't
+	  have the code to drive the on-board Alcatel DSL chipset (yet).
+
+config ATM_ENI
+	tristate "Efficient Networks ENI155P"
+	depends on PCI
+	---help---
+	  Driver for the Efficient Networks ENI155p series and SMC ATM
+	  Power155 155 Mbps ATM adapters. Both, the versions with 512KB and
+	  2MB on-board RAM (Efficient calls them "C" and "S", respectively),
+	  and the FPGA and the ASIC Tonga versions of the board are supported.
+	  The driver works with MMF (-MF or ...F) and UTP-5 (-U5 or ...D)
+	  adapters.
+
+	  To compile this driver as a module, choose M here: the module will
+	  be called eni.
+
+config ATM_ENI_DEBUG
+	bool "Enable extended debugging"
+	depends on ATM_ENI
+	help
+	  Extended debugging records various events and displays that list
+	  when an inconsistency is detected. This mechanism is faster than
+	  generally using printks, but still has some impact on performance.
+	  Note that extended debugging may create certain race conditions
+	  itself. Enable this ONLY if you suspect problems with the driver.
+
+config ATM_ENI_TUNE_BURST
+	bool "Fine-tune burst settings"
+	depends on ATM_ENI
+	---help---
+	  In order to obtain good throughput, the ENI NIC can transfer
+	  multiple words of data per PCI bus access cycle. Such a multi-word
+	  transfer is called a burst.
+
+	  The default settings for the burst sizes are suitable for most PCI
+	  chipsets. However, in some cases, large bursts may overrun buffers
+	  in the PCI chipset and cause data corruption. In such cases, large
+	  bursts must be disabled and only (slower) small bursts can be used.
+	  The burst sizes can be set independently in the send (TX) and
+	  receive (RX) direction.
+
+	  Note that enabling many different burst sizes in the same direction
+	  may increase the cost of setting up a transfer such that the
+	  resulting throughput is lower than when using only the largest
+	  available burst size.
+
+	  Also, sometimes larger bursts lead to lower throughput, e.g. on an
+	  Intel 440FX board, a drop from 135 Mbps to 103 Mbps was observed
+	  when going from 8W to 16W bursts.
+
+config ATM_ENI_BURST_TX_16W
+	bool "Enable 16W TX bursts (discouraged)"
+	depends on ATM_ENI_TUNE_BURST

+
+config ATM_ENI_BURST_TX_8W
+	bool "Enable 8W TX bursts (recommended)"
+	depends on ATM_ENI_TUNE_BURST

+	  setting.
+
+config ATM_ENI_BURST_TX_4W
+	bool "Enable 4W TX bursts (optional)"
+	depends on ATM_ENI_TUNE_BURST
+	help
+	  Burst four words at once in the send direction. You may want to try
+	  this if you have disabled 8W bursts. Enabling 4W if 8W is also set
+	  may or may not improve throughput.
+
+config ATM_ENI_BURST_TX_2W
+	bool "Enable 2W TX bursts (optional)"
+	depends on ATM_ENI_TUNE_BURST
+	help
+	  Burst two words at once in the send direction. You may want to try
+	  this if you have disabled 4W and 8W bursts. Enabling 2W if 4W or 8W
+	  are also set may or may not improve throughput.
+

+
+config ATM_ENI_BURST_RX_4W
+	bool "Enable 4W RX bursts (recommended)"
+	depends on ATM_ENI_TUNE_BURST
+	help
+	  Burst four words at once in the receive direction. This is the

+config ATM_NICSTAR
+	tristate "IDT 77201 (NICStAR) (ForeRunnerLE)"
+	depends on PCI
+	help
+	  The NICStAR chipset family is used in a large number of ATM NICs for
+	  25 and for 155 Mbps, including IDT cards and the Fore ForeRunnerLE
+	  series. Say Y if you have one of those.
+
+	  To compile this driver as a module, choose M here: the module will
+	  be called nicstar.
+
+config ATM_NICSTAR_USE_SUNI
+	bool "Use suni PHY driver (155Mbps)"
+	depends on ATM_NICSTAR
+	help
+	  Support for the S-UNI and compatible PHYsical layer chips. These are
+	  found in most 155Mbps NICStAR based ATM cards, namely in the
+	  ForeRunner LE155 cards. This driver provides detection of cable~
+	  removal and reinsertion and provides some statistics. This driver
+	  doesn't have removal capability when compiled as a module, so if you
+	  need that capability don't include S-UNI support (it's not needed to
+	  make the card work).
+
+config ATM_NICSTAR_USE_IDT77105
+	bool "Use IDT77105 PHY driver (25Mbps)"
+	depends on ATM_NICSTAR
+	help
+	  Support for the PHYsical layer chip in ForeRunner LE25 cards. In
+	  addition to cable removal/reinsertion detection, this driver allows
+	  you to control the loopback mode of the chip via a dedicated IOCTL.
+	  This driver is required for proper handling of temporary carrier
+	  loss, so if you have a 25Mbps NICStAR based ATM card you must say Y.
+
+config ATM_IDT77252
+	tristate "IDT 77252 (NICStAR II)"
+	depends on PCI
+	help
+	  Driver for the IDT 77252 ATM PCI chips.

+
+config ATM_IDT77252_DEBUG
+	bool "Enable debugging messages"
+	depends on ATM_IDT77252
+	help
+	  Somewhat useful debugging messages are available. The choice of
+	  messages is controlled by a bitmap.  This may be specified as a
+	  module argument.  See the file <file:drivers/atm/idt77252.h> for
+	  the meanings of the bits in the mask.
+
+	  When active, these messages can have a significant impact on the
+	  speed of the driver, and the size of your syslog files! When
+	  inactive, they will have only a modest impact on performance.
+
+config ATM_IDT77252_RCV_ALL
+	bool "Receive ALL cells in raw queue"
+	depends on ATM_IDT77252
+	help
+	  Enable receiving of all cells on the ATM link, that do not match

+	  This is a driver for the Interphase (i)ChipSAR adapter cards
+	  which include a variety of variants in term of the size of the
+	  control memory (128K-1KVC, 512K-4KVC), the size of the packet
+	  memory (128K, 512K, 1M), and the PHY type (Single/Multi mode OC3,
+	  UTP155, UTP25, DS3 and E3). Go to:

+	depends on (PCI || SBUS)
+	select FW_LOADER
+	---help---
+	  This is a driver for the FORE Systems 200E-series ATM adapter
+	  cards. It simultaneously supports PCA-200E and SBA-200E models
+	  on PCI and SBUS hosts. Say Y (or M to compile as a module
+	  named fore_200e) here if you have one of these ATM adapters.
+

+
+config ATM_FORE200E_USE_TASKLET
+	bool "Defer interrupt work to a tasklet"
+	depends on ATM_FORE200E
+	default n
+	help
+	  This defers work to be done by the interrupt handler to a
+	  tasklet instead of handling everything at interrupt time.  This
+	  may improve the responsive of the host.
+
+config ATM_FORE200E_TX_RETRY
+	int "Maximum number of tx retries"
+	depends on ATM_FORE200E
+	default "16"
+	---help---
+	  Specifies the number of times the driver attempts to transmit
+	  a message before giving up, if the transmit queue of the ATM card
+	  is transiently saturated.
+
+	  Saturation of the transmit queue may occur only under extreme
+	  conditions, e.g. when a fast host continuously submits very small
+	  frames (<64 bytes) or raw AAL0 cells (48 bytes) to the ATM adapter.
+
+	  Note that under common conditions, it is unlikely that you encounter
+	  a saturation of the transmit queue, so the retry mechanism never
+	  comes into play.
+
+config ATM_FORE200E_DEBUG
+	int "Debugging level (0-3)"
+	depends on ATM_FORE200E
+	default "0"
+	help
+	  Specifies the level of debugging messages issued by the driver.
+	  The verbosity of the driver increases with the value of this
+	  parameter.
+
+	  When active, these messages can have a significant impact on
+	  the performances of the driver, and the size of your syslog files!
+	  Keep the debugging level to 0 during normal operations.
+
+config ATM_HE
+	tristate "ForeRunner HE Series"
+	depends on PCI
+	help
+	  This is a driver for the Marconi ForeRunner HE-series ATM adapter
+	  cards. It simultaneously supports the 155 and 622 versions.

+	bool "Use S/UNI PHY driver"
+	depends on ATM_HE
+	help
+	  Support for the S/UNI-Ultra and S/UNI-622 found in the ForeRunner
+	  HE cards.  This driver provides carrier detection some statistics.
