NAME

       rgephy — RealTek RTL8168/8169/8110/8211 series 10/100/1000 Gigabit Ethernet PHY driver

SYNOPSIS

       To  compile  all  available  PHY  drivers  into  the  kernel,  place  the  following  line in your kernel
       configuration file:

             device miibus

       Alternatively, to selectively compile this driver into the kernel, place  the  following  lines  in  your
       kernel configuration file instead:

             device mii
             device rgephy

DESCRIPTION

       The  rgephy  driver  supports  the  RealTek  RTL8168,  RTL8169,  RTL8110  and  RTL8211  series integrated
       10/100/1000 Gigabit Ethernet PHYs.

       In order to get a list of media types and options supported by a specific instance of the rgephy  driver,
       run ifconfig -m on the instance of its parent MAC driver.

       Additionally, the rgephy driver supports the following special media option:

       flag0  When  manually  setting  media type and options via ifconfig(8), the rgephy driver by default also
              triggers an autonegotiation advertising the selected media.  This is done in order to work  around
              hardware  issues  in  certain scenarios.  It is believed that this behavior does not cause harm in
              general but in fact can have an adverse effect in edge cases.  In order to manually set the  media
              type and options without also triggering an autonegotiation, the rgephy driver allows to turn this
              behavior off via the flag0 media option.

       Note that this special media option will not show up in the output of ifconfig(8), even when set.

EXAMPLES

       Manually set 100BASE-TX full-duplex without also triggering an autonegotiation:

             ifconfig re0 media 100baseTX mediaopt full-duplex,flag0
