NAME
     vr - driver for VIA Rhine fast Ethernet controllers

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

       pci1106,3043 VIA VT86C100A Fast Ethernet
       pci1106,3065 VT6102 VIA Rhine II
       pci1106,3106 VT6105 VIA Rhine III
       pci1106,3053 VT6105 VIA Rhine III Management Adapter




     The vr driver supports  IEEE  802.3  auto-negotiation,  flow
     control and VLAN tagging.

  Configuration
     The default configuration is autonegotiation  with  bidirec-
     tional flow control. The advertised capabilities for autone-
     gotiation are based on the capabilities of the PHY.


     You can set the capabilities advertised by the vr controlled
     device  using  dladm(1M).  The  driver  supports a number of
     parameters, the names of which  begin  with  en_  (enabled).
     Each  of  these  boolean parameters determines if the device
     advertises that mode of operation when the hardware supports
     it.


     The  adv_autoneg_cap  parameter   controls   whether   auto-
     negotiation  is  performed.  If  adv_autoneg_cap  is  0, the
     driver selects the speed/duplex combination from  the  first
     non-zero parameter from this list:

       en_100fdx_cap     100Mpbs full duplex
       en_100hdx_cap     100Mpbs half duplex
       en_10fdx_cap      10Mpbs full duplex
       en_10hdx_cap      10Mpbs half duplex




     All capabilities default to enabled. Changing any capability
     parameter causes the link to go down while the link partners
     renegotiate the link using the newly changed capabilities.

  Limitations
     The vr  driver  does  not  support  asymmetric  flowcontrol.
     VT86C100A   and   Rhine  II  adapters  are  not  capable  of
