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.
config ATM_LANAI
tristate
"Efficient Networks Speedstream 3010"
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.
config ATM_ENI_BURST_TX_16W
bool
"Enable 16W TX bursts (discouraged)"
depends on ATM_ENI_TUNE_BURST
help
Burst sixteen words at once

with recent PCI chipsets, but
is known to fail
with older chipsets.
config ATM_ENI_BURST_TX_8W
bool
"Enable 8W TX bursts (recommended)"
depends on ATM_ENI_TUNE_BURST
help
Burst eight words at once
in the send direction. This
is the default
setting.
config ATM_ENI_BURST_TX_4W
bool
"Enable 4W TX bursts (optional)"
depends on ATM_ENI_TUNE_BURST
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
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.
config ATM_ENI_BURST_RX_16W
bool
"Enable 16W RX bursts (discouraged)"
depends on ATM_ENI_TUNE_BURST
help
Burst sixteen words at once
in the receive direction. This may work

is known to fail
with older chipsets.
config ATM_ENI_BURST_RX_8W
bool
"Enable 8W RX bursts (discouraged)"
depends on ATM_ENI_TUNE_BURST
help
Burst eight words at once

with recent PCI chipsets, but
is known to fail
with older chipsets,
such
as the Intel Neptune series.
config ATM_ENI_BURST_RX_4W
bool
"Enable 4W RX bursts (recommended)"
depends on ATM_ENI_TUNE_BURST
help
Burst four words at once
in the receive direction. This

default setting. Enabling
4W

not
improve throughput.
config ATM_ENI_BURST_RX_2W

depends on ATM_ENI_TUNE_BURST
help
Burst two words at once

4W

2W

config ATM_NICSTAR

help
The NICStAR chipset family

25 and for 155 Mbps, including IDT cards

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).
config ATM_NICSTAR_USE_IDT77105

"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_IDT77252_DEBUG
bool
"Enable debugging messages"

help
Somewhat useful debugging messages are available. The choice of
messages
is controlled by a bitmap. This may be specified
as a
module argument. See the file <file:drivers/atm/idt77252.h>
for
the meanings of the bits
in the mask.
When active, these messages can have a significant impact on the
speed of the driver,

inactive, they will have only a modest impact on performance.

Enable receiving of all cells on the ATM link, that do

is N.

This defers work to be done by the interrupt handler to a
tasklet instead of handling everything at interrupt time. This
may improve the responsive of the host.
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)"

"0"
help
Specifies the level of debugging messages issued by the driver.
The verbosity of the driver increases

parameter.
When active, these messages can have a significant impact on
the performances of the driver,

Keep the debugging level to
0 during normal operations.
