8 vr \- driver for VIA Rhine fast Ethernet controllers
12 The \fBvr\fR Fast Ethernet driver is GLD based and supporting the VIA Rhine
13 family of Fast Ethernet adapters:
17 pci1106,3043 VIA VT86C100A Fast Ethernet
18 pci1106,3065 VT6102 VIA Rhine II
19 pci1106,3106 VT6105 VIA Rhine III
20 pci1106,3053 VT6105 VIA Rhine III Management Adapter
27 The \fBvr\fR driver supports IEEE 802.3 auto-negotiation, flow control and VLAN
32 The default configuration is \fBautonegotiation\fR with bidirectional flow
33 control. The advertised capabilities for \fBautonegotiation\fR are based on the
34 capabilities of the PHY.
37 You can set the capabilities advertised by the \fBvr\fR controlled device using
38 \fBdladm\fR(8). The driver supports a number of parameters, the names of which
39 begin with \fBen_\fR (enabled). Each of these boolean parameters determines if
40 the device advertises that mode of operation when the hardware supports it.
43 The \fBadv_autoneg_cap\fR parameter controls whether auto-negotiation is
44 performed. If \fBadv_autoneg_cap\fR is 0, the driver selects the speed/duplex
45 combination from the first non-zero parameter from this list:
49 en_100fdx_cap 100Mbps full duplex
50 en_100hdx_cap 100Mbps half duplex
51 en_10fdx_cap 10Mbps full duplex
52 en_10hdx_cap 10Mbps half duplex
59 All capabilities default to enabled. Changing any capability parameter causes
60 the link to go down while the link partners renegotiate the link using the
61 newly changed capabilities.
65 The \fBvr\fR driver does not support asymmetric \fBflowcontrol\fR. VT86C100A
66 and Rhine II adapters are not capable of transmitting \fBflowcontrol\fR
