Useful mainly for development and for 29 experiments. If unsure, say N. 30 31config ATM_LANAI 32 tristate "Efficient Networks Speedstream 3010" 33 depends on PCI && ATM 34 help 35 Supports ATM cards based on the Efficient Networks "Lanai" 36 chipset such as the Speedstream 3010 and the ENI-25p. The 37 Speedstream 3060 is currently not supported since we don't 38 have the code to drive the on-board Alcatel DSL chipset (yet). 39 40config ATM_ENI 41 tristate "Efficient Networks ENI155P" 42 depends on PCI 43 help 44 Driver for the Efficient Networks ENI155p series and SMC ATM 45 Power155 155 Mbps ATM adapters. Both, the versions with 512KB and 46 2MB on-board RAM (Efficient calls them "C" and "S", respectively), 47 and the FPGA and the ASIC Tonga versions of the board are supported. 48 The driver works with MMF (-MF or ...F) and UTP-5 (-U5 or ...D) 49 adapters. 50 51 To compile this driver as a module, choose M here: the module will 52 be called eni. 53 54config ATM_ENI_DEBUG 55 bool "Enable extended debugging" 56 depends on ATM_ENI 57 help 58 Extended debugging records various events and displays that list 59 when an inconsistency is detected. This mechanism is faster than 60 generally using printks, but still has some impact on performance. 61 Note that extended debugging may create certain race conditions 62 itself. Enable this ONLY if you suspect problems with the driver. 63 64config ATM_ENI_TUNE_BURST 65 bool "Fine-tune burst settings" 66 depends on ATM_ENI 67 help 68 In order to obtain good throughput, the ENI NIC can transfer 69 multiple words of data per PCI bus access cycle. Such a multi-word 70 transfer is called a burst. 71 72 The default settings for the burst sizes are suitable for most PCI 73 chipsets. However, in some cases, large bursts may overrun buffers 74 in the PCI chipset and cause data corruption. In such cases, large 75 bursts must be disabled and only (slower) small bursts can be used. 76 The burst sizes can be set independently in the send (TX) and 77 receive (RX) direction. 78 79 Note that enabling many different burst sizes in the same direction 80 may increase the cost of setting up a transfer such that the 81 resulting throughput is lower than when using only the largest 82 available burst size. 83 84 Also, sometimes larger bursts lead to lower throughput, e.g. on an 85 Intel 440FX board, a drop from 135 Mbps to 103 Mbps was observed 86 when going from 8W to 16W bursts. 87 88config ATM_ENI_BURST_TX_16W 89 bool "Enable 16W TX bursts (discouraged)" 90 depends on ATM_ENI_TUNE_BURST 91 help 92 Burst sixteen words at once in the send direction.

You may want to try 107 this if you have disabled 8W bursts. Enabling 4W if 8W is also set 108 may or may not improve throughput. 109 110config ATM_ENI_BURST_TX_2W 111 bool "Enable 2W TX bursts (optional)" 112 depends on ATM_ENI_TUNE_BURST 113 help 114 Burst two words at once in the send direction. You may want to try 115 this if you have disabled 4W and 8W bursts. Enabling 2W if 4W or 8W 116 are also set may or may not improve throughput. 117 118config ATM_ENI_BURST_RX_16W 119 bool "Enable 16W RX bursts (discouraged)" 120 depends on ATM_ENI_TUNE_BURST 121 help 122 Burst sixteen words at once in the receive direction. This may work 123 with recent PCI chipsets, but is known to fail with older chipsets. 124 125config ATM_ENI_BURST_RX_8W 126 bool "Enable 8W RX bursts (discouraged)" 127 depends on ATM_ENI_TUNE_BURST 128 help 129 Burst eight words at once in the receive direction. This may work 130 with recent PCI chipsets, but is known to fail with older chipsets, 131 such as the Intel Neptune series. 132 133config ATM_ENI_BURST_RX_4W 134 bool "Enable 4W RX bursts (recommended)" 135 depends on ATM_ENI_TUNE_BURST 136 help 137 Burst four words at once in the receive direction. This is the 138 default setting. Enabling 4W if 8W is also set may or may not 139 improve throughput. 140 141config ATM_ENI_BURST_RX_2W 142 bool "Enable 2W RX bursts (optional)" 143 depends on ATM_ENI_TUNE_BURST 144 help 145 Burst two words at once in the receive direction. You may want to 146 try this if you have disabled 4W and 8W bursts. Enabling 2W if 4W or 147 8W are also set may or may not improve throughput. 148 149config ATM_NICSTAR 150 tristate "IDT 77201 (NICStAR) (ForeRunnerLE)" 151 depends on PCI 152 help 153 The NICStAR chipset family is used in a large number of ATM NICs for 154 25 and for 155 Mbps, including IDT cards and the Fore ForeRunnerLE 155 series. Say Y if you have one of those. 156 157 To compile this driver as a module, choose M here: the module will 158 be called nicstar. 159 160config ATM_NICSTAR_USE_SUNI 161 bool "Use suni PHY driver (155Mbps)" 162 depends on ATM_NICSTAR 163 help 164 Support for the S-UNI and compatible PHYsical layer chips. These are 165 found in most 155Mbps NICStAR based ATM cards, namely in the 166 ForeRunner LE155 cards. This driver provides detection of cable~ 167 removal and reinsertion and provides some statistics. This driver 168 doesn't have removal capability when compiled as a module, so if you 169 need that capability don't include S-UNI support (it's not needed to 170 make the card work). 171 172config ATM_NICSTAR_USE_IDT77105 173 bool "Use IDT77105 PHY driver (25Mbps)" 174 depends on ATM_NICSTAR 175 help 176 Support for the PHYsical layer chip in ForeRunner LE25 cards. In 177 addition to cable removal/reinsertion detection, this driver allows 178 you to control the loopback mode of the chip via a dedicated IOCTL. 179 This driver is required for proper handling of temporary carrier 180 loss, so if you have a 25Mbps NICStAR based ATM card you must say Y. 181 182config ATM_IDT77252 183 tristate "IDT 77252 (NICStAR II)" 184 depends on PCI 185 help 186 Driver for the IDT 77252 ATM PCI chips. 187 188 To compile this driver as a module, choose M here: the module will 189 be called idt77252. 190 191config ATM_IDT77252_DEBUG 192 bool "Enable debugging messages" 193 depends on ATM_IDT77252 194 help 195 Somewhat useful debugging messages are available. The choice of 196 messages is controlled by a bitmap. This may be specified as a 197 module argument. See the file <file:drivers/atm/idt77252.h> for 198 the meanings of the bits in the mask. 199 200 When active, these messages can have a significant impact on the 201 speed of the driver, and the size of your syslog files! When 202 inactive, they will have only a modest impact on performance. 203 204config ATM_IDT77252_RCV_ALL 205 bool "Receive ALL cells in raw queue" 206 depends on ATM_IDT77252 207 help 208 Enable receiving of all cells on the ATM link, that do not match 209 an open connection in the raw cell queue of the driver.

It simultaneously supports PCA-200E and SBA-200E models 258 on PCI and SBUS hosts. Say Y (or M to compile as a module 259 named fore_200e) here if you have one of these ATM adapters. 260 261 See the file 262 <file:Documentation/networking/device_drivers/atm/fore200e.rst> for 263 further details. 264 265config ATM_FORE200E_USE_TASKLET 266 bool "Defer interrupt work to a tasklet" 267 depends on ATM_FORE200E 268 default n 269 help 270 This defers work to be done by the interrupt handler to a 271 tasklet instead of handling everything at interrupt time.
