18config ATM_DUMMY
19	tristate "Dummy ATM driver"
20	help
21	  Dummy ATM driver. Useful for proxy signalling, testing,
22	  and development.  If unsure, say N.

31config ATM_LANAI
32	tristate "Efficient Networks Speedstream 3010"
33	depends on PCI && ATM
34	help
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).

40config ATM_ENI
41	tristate "Efficient Networks ENI155P"
42	depends on PCI
43	help
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)
49	  adapters.
50
51	  To compile this driver as a module, choose M here: the module will
52	  be called eni.
53
54config ATM_ENI_DEBUG
55	bool "Enable extended debugging"
56	depends on ATM_ENI
57	help
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.
63
64config ATM_ENI_TUNE_BURST
65	bool "Fine-tune burst settings"
66	depends on ATM_ENI
67	help
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.
71
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.
78
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
82	  available burst size.
83
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.

95config ATM_ENI_BURST_TX_8W
96	bool "Enable 8W TX bursts (recommended)"
97	depends on ATM_ENI_TUNE_BURST
98	help

102config ATM_ENI_BURST_TX_4W
103	bool "Enable 4W TX bursts (optional)"
104	depends on ATM_ENI_TUNE_BURST
105	help
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.
109
110config ATM_ENI_BURST_TX_2W
111	bool "Enable 2W TX bursts (optional)"
112	depends on ATM_ENI_TUNE_BURST
113	help
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.
117
118config ATM_ENI_BURST_RX_16W
119	bool "Enable 16W RX bursts (discouraged)"
120	depends on ATM_ENI_TUNE_BURST

125config ATM_ENI_BURST_RX_8W
126	bool "Enable 8W RX bursts (discouraged)"
127	depends on ATM_ENI_TUNE_BURST
128	help

135	depends on ATM_ENI_TUNE_BURST
136	help
137	  Burst four words at once in the receive direction. This is the

151	depends on PCI
152	help
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.

160config ATM_NICSTAR_USE_SUNI
161	bool "Use suni PHY driver (155Mbps)"
162	depends on ATM_NICSTAR
163	help
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
170	  make the card work).
171

173	bool "Use IDT77105 PHY driver (25Mbps)"
174	depends on ATM_NICSTAR
175	help
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.

194	help
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.
199
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.

254	select FW_LOADER
255	help
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

278	help
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.
282
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.
286
287	  Note that under common conditions, it is unlikely that you encounter
288	  a saturation of the transmit queue, so the retry mechanism never
289	  comes into play.
