          device drivers. This option alone does not add any kernel code.

config ATM_DUMMY
        tristate "Dummy ATM driver"
        help
          Dummy ATM driver. Useful for proxy signalling, testing,
          and development.  If unsure, say N.

        depends on INET
        help
          ATM over TCP driver. Useful mainly for development and for
          experiments. If unsure, say N.

config ATM_LANAI

        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.

        depends on ATM_ENI_TUNE_BURST

          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.

        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.

          such as the Intel Neptune series.

config ATM_ENI_BURST_RX_4W

        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.

          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.
