38 .Nd "Alteon Networks Tigon I and Tigon II gigabit ethernet driver"
44 driver provides support for PCI gigabit ethernet adapters based on
45 the Alteon Networks Tigon gigabit ethernet controller chip.
47 contains an embedded R4000 CPU, gigabit MAC, dual DMA channels and
49 The Tigon II contains two R4000 CPUs and other
51 Either chip can be used in either a 32-bit or 64-bit PCI
53 Communication with the chip is achieved via PCI shared memory
55 The Tigon I and II support hardware multicast
56 address filtering, VLAN tag extraction and insertion, and jumbo
57 ethernet frames sizes up to 9000 bytes.
58 Note that the Tigon I chipset
59 is no longer in active production: all new adapters should come equipped
60 with Tigon II chipsets.
62 There are several PCI boards available from both Alteon and other
63 vendors that use the Tigon chipset under OEM contract.
66 driver has been tested with the following Tigon-based adapters:
68 .Bl -bullet -compact -offset indent
70 The Alteon AceNIC V gigabit ethernet adapter (1000baseSX)
72 The Alteon AceNIC V gigabit ethernet adapter (1000baseT)
74 The 3Com 3c985-SX gigabit ethernet adapter (Tigon 1)
76 The 3Com 3c985B-SX gigabit ethernet adapter (Tigon 2)
78 The Netgear GA620 gigabit ethernet adapter (1000baseSX)
80 The Netgear GA620T gigabit ethernet adapter (1000baseT)
83 The following should also be supported but have not yet been tested:
85 .Bl -bullet -compact -offset indent
87 The Digital EtherWORKS 1000SX PCI Gigabit Adapter
89 Silicon Graphics PCI gigabit ethernet adapter
91 Farallon PN9000SX Gigabit Ethernet adapter
94 While the Tigon chipset supports 10, 100 and 1000Mbps speeds, support for
95 10 and 100Mbps speeds is only available on boards with the proper
97 Most adapters are only designed to work at 1000Mbps,
98 however the driver should support those NICs that work at lower speeds
101 Support for jumbo frames is provided via the interface MTU setting.
102 Selecting an MTU larger than 1500 bytes with the
104 utility configures the adapter to receive and transmit jumbo frames.
105 Using jumbo frames can greatly improve performance for certain tasks,
106 such as file transfers and data streaming.
108 Support for vlans is also available using the
113 man page for more details.
117 driver supports the following media types:
119 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
121 Enable autoselection of the media type and options.
122 The user can manually override
123 the autoselected mode by adding media options to the
127 Set 10Mbps operation.
130 option can also be used to select either
136 Set 100Mbps (fast ethernet) operation.
139 option can also be used to select either
145 Set 1000Mbps (gigabit ethernet) operation.
148 mode is supported at this speed.
153 driver supports the following media options:
155 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
157 Force full duplex operation
159 Force half duplex operation.
162 For more information on configuring this device, see
166 .It "ti%d: couldn't map memory"
167 A fatal initialization error has occurred.
168 .It "ti%d: couldn't map interrupt"
169 A fatal initialization error has occurred.
170 .It "ti%d: no memory for softc struct!"
171 The driver failed to allocate memory for per-device instance information
172 during initialization.
173 .It "ti%d: failed to enable memory mapping!"
174 The driver failed to initialize PCI shared memory mapping.
176 happen if the card is not in a bus-master slot.
177 .It "ti%d: no memory for jumbo buffers!"
178 The driver failed to allocate memory for jumbo frames during
180 .It "ti%d: bios thinks we're in a 64 bit slot, but we aren't"
181 The BIOS has programmed the NIC as though it had been installed in
182 a 64-bit PCI slot, but in fact the NIC is in a 32-bit slot.
184 as a result of a bug in some BIOSes.
185 This can be worked around on the
186 Tigon II, but on the Tigon I initialization will fail.
187 .It "ti%d: board self-diagnostics failed!"
188 The ROMFAIL bit in the CPU state register was set after system
189 startup, indicating that the on-board NIC diagnostics failed.
190 .It "ti%d: unknown hwrev"
191 The driver detected a board with an unsupported hardware revision.
194 driver supports revision 4 (Tigon 1) and revision 6 (Tigon 2) chips
195 and has firmware only for those devices.
196 .It "ti%d: watchdog timeout"
197 The device has stopped responding to the network, or there is a problem with
198 the network connection (cable).
