SYNOPSIS
     epic* at pci?

DESCRIPTION
     The epic interface provides access to the 10Mb/s and 100Mb/s Ethernet
     networks via the SMC EPIC chipset.  This driver provides support for the
     SMC EtherPower II 10/100 Ethernet cards.

     The epic supports several media types, which are selected via the
     ifconfig(8) command.  The supported media types are:

           media autoselect
                   Attempt to autoselect the media type (default)

           media 100baseFX mediaopt full-duplex
                   Use 100baseFX (fiber), full duplex

           media 100baseFX [mediaopt half-duplex]
                   Use 100baseFX (fiber), half duplex

           media 100baseTX mediaopt full-duplex
                   Use 100baseTX, full duplex

           media 100baseTX [mediaopt half-duplex]
                   Use 100baseTX, half duplex

           media 100baseTX mediaopt loopback
                   Put the interface into loopback mode

           media 10baseT mediaopt full-duplex
                   Use 10baseT, full duplex

           media 10baseT [mediaopt half-duplex]
                   Use 10baseT, half duplex

           media 10baseT mediaopt loopback
