| 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. |

| 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 |

| 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). |

| 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_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)" |

| 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. |
