6 vr - driver for VIA Rhine fast Ethernet controllers

9 The vr Fast Ethernet driver is GLD based and supporting the VIA Rhine
10 family of Fast Ethernet adapters:

13 pci1106,3065 VT6102 VIA Rhine II

15 pci1106,3053 VT6105 VIA Rhine III Management Adapter

20 The vr driver supports IEEE 802.3 auto-negotiation, flow control and
21 VLAN tagging.
22
23 Configuration
24 The default configuration is autonegotiation with bidirectional flow
25 control. The advertised capabilities for autonegotiation are based on
26 the capabilities of the PHY.
27
28
29 You can set the capabilities advertised by the vr controlled device
30 using dladm(1M). The driver supports a number of parameters, the names
31 of which begin with en_ (enabled). Each of these boolean parameters
32 determines if the device advertises that mode of operation when the
33 hardware supports it.
34
35
36 The adv_autoneg_cap parameter controls whether auto-negotiation is per‐
37 formed. If adv_autoneg_cap is 0, the driver selects the speed/duplex
38 combination from the first non-zero parameter from this list:
39
40 en_100fdx_cap 100Mpbs full duplex
41 en_100hdx_cap 100Mpbs half duplex
42 en_10fdx_cap 10Mpbs full duplex
43 en_10hdx_cap 10Mpbs half duplex
44
45
46
47
48 All capabilities default to enabled. Changing any capability parameter
49 causes the link to go down while the link partners renegotiate the link
50 using the newly changed capabilities.
51
52 Limitations
53 The vr driver does not support asymmetric flowcontrol. VT86C100A and
54 Rhine II adapters are not capable of transmitting flowcontrol messages
