| 31 | .Sh NAME |
| 32 | .Nm de |
| 33 | .Nd DEC DC21x4x Ethernet device driver |
| 34 | .Sh SYNOPSIS |
| 35 | .Cd "device de" |
| 36 | .Sh DESCRIPTION |
| 37 | The |
| 38 | .Nm |
| 39 | driver provides support for the Ethernet adapters based on the Digital |
| 40 | Equipment DC21x4x based self-contained Ethernet chips. |
| 41 | .Pp |
| 42 | It supports the DEC PCI DE435 card, DEC DE450, DEC DE500, |
| 43 | SMC 8432, 9332 and 9334, Cogent EM100FX and EM440TX, Asante, |
| 44 | ZNYX ZX3xx, and others based on the 21040 and 21041 Ethernet controllers or |
| 45 | the 21140[A], 21141, 21142 and 21143 Fast 100Mbps Ethernet controllers. |
| 46 | .Pp |
| 47 | The |
| 48 | .Nm |
| 49 | driver supports the following media types: |
| 50 | .Bl -tag -width xxxxxxxxxxxxxxx |
| 51 | .It autoselect |
| 52 | Enable autoselection of the media type and options |
| 53 | .It 10baseT/UTP |
| 54 | Set 10Mbps operation on the 10baseT port |
| 55 | .It 10base2/BNC |
| 56 | Set 10Mbps operation on the BNC port |
| 57 | .It 10base5/AUI |
| 58 | Set 10Mbps operation on the AUI port |
| 59 | .It 100baseTX |
| 60 | Set 100Mbps (fast ethernet) operation |
| 61 | .It 100baseFX |
| 62 | Set 100Mbps operation |
| 63 | .It 100baseT4 |
| 64 | Set 100Mbps operation (4-pair cat-3 cable) |
| 65 | .El |
| 66 | .Pp |
| 67 | The |
| 68 | .Nm |
| 69 | driver supports the following media options: |
| 70 | .Bl -tag -width xxxxxxxxxxxxxxx |
| 71 | .It full-duplex |
| 72 | Set full duplex operation |
| 73 | .El |
| 74 | .Pp |
| 75 | Note that the media types available depend on the particular card in use. |
| 76 | Some cards are explicitly programmed to a particular media type by a |
| 77 | setup utility and are not changeable. |
| 78 | .Pp |
| 79 | Use the |
| 80 | .Xr ifconfig 8 |
| 81 | command an in particular the |
| 82 | .Fl m |
| 83 | flag to list the supported media types for your particular card. |
| 84 | .Pp |
| 85 | The old |
| 86 | .Dq ifconfig linkN |
| 87 | method of configuration is not supported. |
| 88 | .Sh DIAGNOSTICS |
| 89 | .Bl -diag |
| 90 | .It "de%d: waking device from sleep/snooze mode" |
| 91 | The 21041 and 21140A chips support suspending the operation of the card. |
| 92 | .It "de%d: error: desired IRQ of %d does not match device's actual IRQ of %d" |
| 93 | The device probe detected that the board is configured for a different |
| 94 | interrupt than the one specified in the kernel configuration file. |
| 95 | .It "de%d: not configured; limit of %d reached or exceeded" |
| 96 | There is a limit of 32 |
| 97 | .Nm |
| 98 | devices allowed in a single machine. |
| 99 | .It "de%d: not configured; 21040 pass 2.0 required (%d.%d found)" |
| 100 | .It "de%d: not configured; 21140 pass 1.1 required (%d.%d found)" |
| 101 | Certain revisions of the chipset are not supported by this driver. |
