This option alone does not add any kernel code. If you say N, all options in this submenu will be skipped and disabled. if ATM_DRIVERS && NETDEVICES && ATM config ATM_DUMMY tristate "Dummy ATM driver" help Dummy ATM driver. Useful for proxy signalling, testing, and development. If unsure, say N. config ATM_TCP tristate "ATM over TCP" depends on INET help ATM over TCP driver. Useful mainly for development and for experiments. If unsure, say N. 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 help Burst sixteen words at once in the send direction. This may work with recent PCI chipsets, but is known to fail with older chipsets. config ATM_ENI_BURST_TX_8W bool "Enable 8W TX bursts (recommended)" depends on ATM_ENI_TUNE_BURST help Burst eight words at once in the send direction. This is the default 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_16W bool "Enable 16W RX bursts (discouraged)" depends on ATM_ENI_TUNE_BURST help Burst sixteen words at once in the receive direction. This may work with recent PCI chipsets, but is known to fail with older chipsets. config ATM_ENI_BURST_RX_8W bool "Enable 8W RX bursts (discouraged)" depends on ATM_ENI_TUNE_BURST help Burst eight words at once in the receive direction. This may work with recent PCI chipsets, but is known to fail with older chipsets, such as the Intel Neptune series. 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 default setting. Enabling 4W if 8W is also set may or may not improve throughput. config ATM_ENI_BURST_RX_2W bool "Enable 2W RX bursts (optional)" depends on ATM_ENI_TUNE_BURST help Burst two words at once in the receive 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_FIRESTREAM tristate "Fujitsu FireStream (FS50/FS155) " depends on PCI && VIRT_TO_BUS help Driver for the Fujitsu FireStream 155 (MB86697) and FireStream 50 (MB86695) ATM PCI chips. To compile this driver as a module, choose M here: the module will be called firestream. config ATM_ZATM tristate "ZeitNet ZN1221/ZN1225" depends on PCI && VIRT_TO_BUS help Driver for the ZeitNet ZN1221 (MMF) and ZN1225 (UTP-5) 155 Mbps ATM adapters. To compile this driver as a module, choose M here: the module will be called zatm. config ATM_ZATM_DEBUG bool "Enable extended debugging" depends on ATM_ZATM 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_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. To compile this driver as a module, choose M here: the module will be called idt77252. 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 an open connection in the raw cell queue of the driver. Useful for debugging or special applications only, so the safe answer is N. config ATM_IDT77252_USE_SUNI bool depends on ATM_IDT77252 default y config ATM_AMBASSADOR tristate "Madge Ambassador (Collage PCI 155 Server)" depends on PCI && VIRT_TO_BUS select BITREVERSE help This is a driver for ATMizer based ATM card produced by Madge Networks Ltd. Say Y (or M to compile as a module named ambassador) here if you have one of these cards. config ATM_AMBASSADOR_DEBUG bool "Enable debugging messages" depends on ATM_AMBASSADOR help Somewhat useful debugging messages are available. The choice of messages is controlled by a bitmap. This may be specified as a module argument (kernel command line argument as well?), changed dynamically using an ioctl (not yet) or changed by sending the string "Dxxxx" to VCI 1023 (where x is a hex digit). See the file <file:drivers/atm/ambassador.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_HORIZON tristate "Madge Horizon [Ultra] (Collage PCI 25 and Collage PCI 155 Client)" depends on PCI && VIRT_TO_BUS help This is a driver for the Horizon chipset ATM adapter cards once produced by Madge Networks Ltd. Say Y (or M to compile as a module named horizon) here if you have one of these cards. config ATM_HORIZON_DEBUG bool "Enable debugging messages" depends on ATM_HORIZON help Somewhat useful debugging messages are available. The choice of messages is controlled by a bitmap. This may be specified as a module argument (kernel command line argument as well?), changed dynamically using an ioctl (not yet) or changed by sending the string "Dxxxx" to VCI 1023 (where x is a hex digit). See the file <file:drivers/atm/horizon.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_IA tristate "Interphase ATM PCI x575/x525/x531" depends on PCI help 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: <http://www.iphase.com/> for more info about the cards. Say Y (or M to compile as a module named iphase) here if you have one of these cards. See the file <file:Documentation/networking/device_drivers/atm/iphase.rst> for further details. config ATM_IA_DEBUG bool "Enable debugging messages" depends on ATM_IA help Somewhat useful debugging messages are available. The choice of messages is controlled by a bitmap. This may be specified as a module argument (kernel command line argument as well?), changed dynamically using an ioctl (Get the debug utility, iadbg, from <ftp://ftp.iphase.com/pub/atm/pci/>). See the file <file:drivers/atm/iphase.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_FORE200E tristate "FORE Systems 200E-series" 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. See the file <file:Documentation/networking/device_drivers/atm/fore200e.rst> for further details. 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. config ATM_HE_USE_SUNI 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. config ATM_SOLOS tristate "Solos ADSL2+ PCI Multiport card driver" depends on PCI select FW_LOADER help Support for the Solos multiport ADSL2+ card. endif # ATM
