The37 Speedstream 3060 is currently not supported since we don't38 have the code to drive the on-board Alcatel DSL chipset (yet).39 40config ATM_ENI41 tristate "Efficient Networks ENI155P"42 depends on PCI43 help44 Driver for the Efficient Networks ENI155p series and SMC ATM45 Power155 155 Mbps ATM adapters. Both, the versions with 512KB and46 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 will52 be called eni.53 54config ATM_ENI_DEBUG55 bool "Enable extended debugging"56 depends on ATM_ENI57 help58 Extended debugging records various events and displays that list59 when an inconsistency is detected. This mechanism is faster than60 generally using printks, but still has some impact on performance.61 Note that extended debugging may create certain race conditions62 itself. Enable this ONLY if you suspect problems with the driver.63 64config ATM_ENI_TUNE_BURST65 bool "Fine-tune burst settings"66 depends on ATM_ENI67 help68 In order to obtain good throughput, the ENI NIC can transfer69 multiple words of data per PCI bus access cycle. Such a multi-word70 transfer is called a burst.71 72 The default settings for the burst sizes are suitable for most PCI73 chipsets. However, in some cases, large bursts may overrun buffers74 in the PCI chipset and cause data corruption. In such cases, large75 bursts must be disabled and only (slower) small bursts can be used.76 The burst sizes can be set independently in the send (TX) and77 receive (RX) direction.78 79 Note that enabling many different burst sizes in the same direction80 may increase the cost of setting up a transfer such that the81 resulting throughput is lower than when using only the largest82 available burst size.83 84 Also, sometimes larger bursts lead to lower throughput, e.g. on an85 Intel 440FX board, a drop from 135 Mbps to 103 Mbps was observed86 when going from 8W to 16W bursts.87 88config ATM_ENI_BURST_TX_16W89 bool "Enable 16W TX bursts (discouraged)"90 depends on ATM_ENI_TUNE_BURST91 help92 Burst sixteen words at once in the send direction.

This is the138 default setting. Enabling 4W if 8W is also set may or may not139 improve throughput.140 141config ATM_ENI_BURST_RX_2W142 bool "Enable 2W RX bursts (optional)"143 depends on ATM_ENI_TUNE_BURST144 help145 Burst two words at once in the receive direction. You may want to146 try this if you have disabled 4W and 8W bursts. Enabling 2W if 4W or147 8W are also set may or may not improve throughput.148 149config ATM_NICSTAR150 tristate "IDT 77201 (NICStAR) (ForeRunnerLE)"151 depends on PCI152 help153 The NICStAR chipset family is used in a large number of ATM NICs for154 25 and for 155 Mbps, including IDT cards and the Fore ForeRunnerLE155 series.

These are165 found in most 155Mbps NICStAR based ATM cards, namely in the166 ForeRunner LE155 cards. This driver provides detection of cable~167 removal and reinsertion and provides some statistics. This driver168 doesn't have removal capability when compiled as a module, so if you169 need that capability don't include S-UNI support (it's not needed to170 make the card work).171 172config ATM_NICSTAR_USE_IDT77105173 bool "Use IDT77105 PHY driver (25Mbps)"174 depends on ATM_NICSTAR175 help176 Support for the PHYsical layer chip in ForeRunner LE25 cards. In177 addition to cable removal/reinsertion detection, this driver allows178 you to control the loopback mode of the chip via a dedicated IOCTL.179 This driver is required for proper handling of temporary carrier180 loss, so if you have a 25Mbps NICStAR based ATM card you must say Y.181 182config ATM_IDT77252183 tristate "IDT 77252 (NICStAR II)"184 depends on PCI185 help186 Driver for the IDT 77252 ATM PCI chips.187 188 To compile this driver as a module, choose M here: the module will189 be called idt77252.190 191config ATM_IDT77252_DEBUG192 bool "Enable debugging messages"193 depends on ATM_IDT77252194 help195 Somewhat useful debugging messages are available.
