config ATM_DUMMY

        help

          Dummy ATM driver. Useful for proxy signalling, testing,

          and development.  If unsure, say N.

        help

          ATM over TCP driver. Useful mainly for development and for

          experiments. If unsure, say N.

        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

        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.

          this if you have disabled 8W bursts. Enabling 4W if 8W is also set

          may or may not improve throughput.

        help

          25 and for 155 Mbps, including IDT cards and the Fore ForeRunnerLE

          series. Say Y if you have one of those.

          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).

          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.
