11 Say Y here to get to see options for Asynchronous Transfer Mode
12 device drivers. This option alone does not add any kernel code.
14 If you say N, all options in this submenu will be skipped and disabled.

19 tristate "Dummy ATM driver"
21 Dummy ATM driver. Useful for proxy signalling, testing,
22 and development. If unsure, say N.
25 tristate "ATM over TCP"
28 ATM over TCP driver. Useful mainly for development and for
29 experiments. If unsure, say N.
32 tristate "Efficient Networks Speedstream 3010"
35 Supports ATM cards based on the Efficient Networks "Lanai"
36 chipset such as the Speedstream 3010 and the ENI-25p. The
37 Speedstream 3060 is currently not supported since we don't
38 have the code to drive the on-board Alcatel DSL chipset (yet).
41 tristate "Efficient Networks ENI155P"
44 Driver for the Efficient Networks ENI155p series and SMC ATM
45 Power155 155 Mbps ATM adapters. Both, the versions with 512KB and
46 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)

55 bool "Enable extended debugging"
58 Extended debugging records various events and displays that list
59 when an inconsistency is detected. This mechanism is faster than
60 generally using printks, but still has some impact on performance.
61 Note that extended debugging may create certain race conditions
62 itself. Enable this ONLY if you suspect problems with the driver.
64 config ATM_ENI_TUNE_BURST
65 bool "Fine-tune burst settings"
68 In order to obtain good throughput, the ENI NIC can transfer
69 multiple words of data per PCI bus access cycle. Such a multi-word
70 transfer is called a burst.
72 The default settings for the burst sizes are suitable for most PCI
73 chipsets. However, in some cases, large bursts may overrun buffers
74 in the PCI chipset and cause data corruption. In such cases, large
75 bursts must be disabled and only (slower) small bursts can be used.
76 The burst sizes can be set independently in the send (TX) and
77 receive (RX) direction.
79 Note that enabling many different burst sizes in the same direction
80 may increase the cost of setting up a transfer such that the
81 resulting throughput is lower than when using only the largest
84 Also, sometimes larger bursts lead to lower throughput, e.g. on an
85 Intel 440FX board, a drop from 135 Mbps to 103 Mbps was observed
86 when going from 8W to 16W bursts.
88 config ATM_ENI_BURST_TX_16W
89 bool "Enable 16W TX bursts (discouraged)"
90 depends on ATM_ENI_TUNE_BURST
92 Burst sixteen words at once in the send direction. This may work
93 with recent PCI chipsets, but is known to fail with older chipsets.
95 config ATM_ENI_BURST_TX_8W
96 bool "Enable 8W TX bursts (recommended)"
97 depends on ATM_ENI_TUNE_BURST
99 Burst eight words at once in the send direction. This is the default
102 config ATM_ENI_BURST_TX_4W
103 bool "Enable 4W TX bursts (optional)"
104 depends on ATM_ENI_TUNE_BURST
106 Burst four words at once in the send direction. You may want to try
107 this if you have disabled 8W bursts. Enabling 4W if 8W is also set
108 may or may not improve throughput.
110 config ATM_ENI_BURST_TX_2W
111 bool "Enable 2W TX bursts (optional)"
112 depends on ATM_ENI_TUNE_BURST
114 Burst two words at once in the send direction. You may want to try
115 this if you have disabled 4W and 8W bursts. Enabling 2W if 4W or 8W
116 are also set may or may not improve throughput.
118 config ATM_ENI_BURST_RX_16W
119 bool "Enable 16W RX bursts (discouraged)"
120 depends on ATM_ENI_TUNE_BURST
122 Burst sixteen words at once in the receive direction. This may work
123 with recent PCI chipsets, but is known to fail with older chipsets.
125 config ATM_ENI_BURST_RX_8W
126 bool "Enable 8W RX bursts (discouraged)"
127 depends on ATM_ENI_TUNE_BURST
129 Burst eight words at once in the receive direction. This may work
130 with recent PCI chipsets, but is known to fail with older chipsets,
131 such as the Intel Neptune series.
133 config ATM_ENI_BURST_RX_4W
134 bool "Enable 4W RX bursts (recommended)"
135 depends on ATM_ENI_TUNE_BURST
137 Burst four words at once in the receive direction. This is the
138 default setting. Enabling 4W if 8W is also set may or may not
141 config ATM_ENI_BURST_RX_2W
142 bool "Enable 2W RX bursts (optional)"
143 depends on ATM_ENI_TUNE_BURST
145 Burst two words at once in the receive direction. You may want to
146 try this if you have disabled 4W and 8W bursts. Enabling 2W if 4W or
147 8W are also set may or may not improve throughput.
150 tristate "IDT 77201 (NICStAR) (ForeRunnerLE)"
153 The NICStAR chipset family is used in a large number of ATM NICs for
154 25 and for 155 Mbps, including IDT cards and the Fore ForeRunnerLE
155 series. Say Y if you have one of those.
157 To compile this driver as a module, choose M here: the module will
160 config ATM_NICSTAR_USE_SUNI
161 bool "Use suni PHY driver (155Mbps)"
162 depends on ATM_NICSTAR
164 Support for the S-UNI and compatible PHYsical layer chips. These are
165 found in most 155Mbps NICStAR based ATM cards, namely in the
166 ForeRunner LE155 cards. This driver provides detection of cable~
167 removal and reinsertion and provides some statistics. This driver
168 doesn't have removal capability when compiled as a module, so if you
169 need that capability don't include S-UNI support (it's not needed to
172 config ATM_NICSTAR_USE_IDT77105
173 bool "Use IDT77105 PHY driver (25Mbps)"
174 depends on ATM_NICSTAR
176 Support for the PHYsical layer chip in ForeRunner LE25 cards. In
177 addition to cable removal/reinsertion detection, this driver allows
178 you to control the loopback mode of the chip via a dedicated IOCTL.
179 This driver is required for proper handling of temporary carrier
180 loss, so if you have a 25Mbps NICStAR based ATM card you must say Y.
183 tristate "IDT 77252 (NICStAR II)"
186 Driver for the IDT 77252 ATM PCI chips.
188 To compile this driver as a module, choose M here: the module will
191 config ATM_IDT77252_DEBUG
192 bool "Enable debugging messages"
193 depends on ATM_IDT77252
195 Somewhat useful debugging messages are available. The choice of
196 messages is controlled by a bitmap. This may be specified as a
197 module argument. See the file <file:drivers/atm/idt77252.h> for
198 the meanings of the bits in the mask.
200 When active, these messages can have a significant impact on the
201 speed of the driver, and the size of your syslog files! When
202 inactive, they will have only a modest impact on performance.
204 config ATM_IDT77252_RCV_ALL
205 bool "Receive ALL cells in raw queue"
206 depends on ATM_IDT77252
208 Enable receiving of all cells on the ATM link, that do not match
209 an open connection in the raw cell queue of the driver. Useful
210 for debugging or special applications only, so the safe answer is N.

214 depends on ATM_IDT77252
218 tristate "Interphase ATM PCI x575/x525/x531"
221 This is a driver for the Interphase (i)ChipSAR adapter cards
222 which include a variety of variants in term of the size of the
223 control memory (128K-1KVC, 512K-4KVC), the size of the packet
224 memory (128K, 512K, 1M), and the PHY type (Single/Multi mode OC3,
225 UTP155, UTP25, DS3 and E3). Go to:
226 <http://www.iphase.com/>
227 for more info about the cards. Say Y (or M to compile as a module
228 named iphase) here if you have one of these cards.
231 <file:Documentation/networking/device_drivers/atm/iphase.rst>
235 bool "Enable debugging messages"
238 Somewhat useful debugging messages are available. The choice of
239 messages is controlled by a bitmap. This may be specified as a
240 module argument (kernel command line argument as well?), changed
241 dynamically using an ioctl (Get the debug utility, iadbg, from
242 <ftp://ftp.iphase.com/pub/atm/pci/>).

249 inactive, they will have only a modest impact on performance.
252 tristate "FORE Systems 200E-series"
253 depends on (PCI || SBUS)
256 This is a driver for the FORE Systems 200E-series ATM adapter
257 cards. It simultaneously supports PCA-200E and SBA-200E models
258 on PCI and SBUS hosts. Say Y (or M to compile as a module
259 named fore_200e) here if you have one of these ATM adapters.

265 config ATM_FORE200E_USE_TASKLET
266 bool "Defer interrupt work to a tasklet"
267 depends on ATM_FORE200E
270 This defers work to be done by the interrupt handler to a
271 tasklet instead of handling everything at interrupt time. This
272 may improve the responsive of the host.
274 config ATM_FORE200E_TX_RETRY
275 int "Maximum number of tx retries"
276 depends on ATM_FORE200E
279 Specifies the number of times the driver attempts to transmit
280 a message before giving up, if the transmit queue of the ATM card
281 is transiently saturated.
283 Saturation of the transmit queue may occur only under extreme
284 conditions, e.g. when a fast host continuously submits very small
285 frames (<64 bytes) or raw AAL0 cells (48 bytes) to the ATM adapter.
287 Note that under common conditions, it is unlikely that you encounter
288 a saturation of the transmit queue, so the retry mechanism never
291 config ATM_FORE200E_DEBUG
292 int "Debugging level (0-3)"
293 depends on ATM_FORE200E
296 Specifies the level of debugging messages issued by the driver.
297 The verbosity of the driver increases with the value of this

301 the performances of the driver, and the size of your syslog files!
302 Keep the debugging level to 0 during normal operations.
305 tristate "ForeRunner HE Series"
308 This is a driver for the Marconi ForeRunner HE-series ATM adapter
309 cards. It simultaneously supports the 155 and 622 versions.
311 config ATM_HE_USE_SUNI
312 bool "Use S/UNI PHY driver"
315 Support for the S/UNI-Ultra and S/UNI-622 found in the ForeRunner
316 HE cards. This driver provides carrier detection some statistics.
