40.Nd Alteon Networks Tigon I and II Gigabit Ethernet device
41.Sh SYNOPSIS
42.Cd "ti* at pci?"
43.Cd "ti* at sbus?"
44.Sh DESCRIPTION
45The
46.Nm
47driver provides support for Gigabit Ethernet adapters based on the
48Alteon Networks Tigon Gigabit Ethernet controller chip, including
49the following:
50.Pp
51.Bl -bullet -compact -offset indent

73Sun Vector Gigabit Ethernet (1000baseSX)
74.El
75.Pp
76The Tigon contains an embedded R4000 CPU, Gigabit MAC, dual DMA channels and
77a PCI interface unit.
78The Tigon II contains two R4000 CPUs and other refinements.
79Either chip can be used in either a 32-bit or 64-bit PCI slot.
80Communication with the chip is achieved via PCI shared memory and
81bus master DMA.
82SBus cards are also available and use a special bridge chip.
83The Tigon I and II support hardware multicast address filtering,
84VLAN tag insertion and stripping, and jumbo frames.
85.Pp
86While the Tigon chipset supports 10, 100 and 1000Mbps speeds, support for
8710 and 100Mbps speeds is only available on boards with the proper
88transceivers.
89Most adapters are only designed to work at 1000Mbps, however the driver
90should support those NICs that work at lower speeds as well.
91.Pp
92The
93.Nm
94driver supports the following media types:
95.Bl -tag -width full-duplex
96.It autoselect
97Enable autoselection of the media type and options.
98The user can manually override
99the autoselected mode by adding media options to the appropriate
100.Xr hostname.if 5
101file.
102.It 10baseT
103Set 10Mbps operation
104The
105.Ar mediaopt
106option can also be used to select either
107.Ar full-duplex
108or
109.Ar half-duplex
110modes.
111.It 100baseTX
112Set 100Mbps (Fast Ethernet) operation.
113The
114.Ar mediaopt
115option can also be used to select either
116.Ar full-duplex
117or
118.Ar half-duplex
119modes.
120.It 1000baseSX
121Set 1000Mbps (Gigabit Ethernet) on fiber operation.
122Only
123.Ar full-duplex
124mode is supported at this speed.
125.It 1000baseT
126Set 1000Mbps (Gigabit Ethernet) on copper operation.
127.El
128.Pp
129The
130.Nm
131driver supports the following media options:
132.Bl -tag -width full-duplex
133.It full-duplex
134Force full duplex operation
135.It half-duplex
136Force half duplex operation
137.El
138.Pp
139For more information on configuring this device, see
140.Xr ifconfig 8 .
141.Sh FILES
142Two firmware files are necessary, for Tigon 1 and Tigon 2 devices.
143These are loaded on demand
144when the device is attached:
145.Pp
146.Bl -tag -width Ds -offset indent -compact
147.It Pa /etc/firmware/tigon1
148.It Pa /etc/firmware/tigon2
149.El
150.Sh DIAGNOSTICS
151.Bl -diag
152.It "ti0: couldn't map memory"
153A fatal initialization error has occurred.
154.It "ti0: couldn't map interrupt"
155A fatal initialization error has occurred.
156.It "ti0: no memory for softc struct!"
157The driver failed to allocate memory for per-device instance information
158during initialization.
159.It "ti0: failed to enable memory mapping!"
160The driver failed to initialize PCI shared memory mapping.
161This might happen if the card is not in a bus-master slot.
162.It "ti0: no memory for jumbo buffers!"
163The driver failed to allocate memory for jumbo frames during
164initialization.
165.It "ti0: bios thinks we're in a 64 bit slot, but we aren't"
166The BIOS has programmed the NIC as though it had been installed in
167a 64-bit PCI slot, but in fact the NIC is in a 32-bit slot.
168This happens as a result of a bug in some BIOSes.
169This can be worked around on the Tigon II, but
170on the Tigon I initialization will fail.
171.It "ti0: board self-diagnostics failed!"
172The ROMFAIL bit in the CPU state register was set after system
173startup, indicating that the on-board NIC diagnostics failed.
174.It "ti0: unknown hwrev"
175The driver detected a board with an unsupported hardware revision.
176The
177.Nm
178driver supports revision 4 (Tigon 1) and revision 6 (Tigon 2) chips
179and has firmware only for those devices.
180.It "ti0: watchdog timeout -- resetting"
181The device has stopped responding to the network, or there is a problem with
182the network connection (cable).
