DESCRIPTION

     Media Independent Interface is an IEEE standard serial bus for connecting MACs (network controllers) to PHYs (physical media interfaces).
     The mii layer allows network device drivers to share support code for various PHY models, and allows unused support for PHYs which are not
     present in a system to be removed from the kernel.

     Network device drivers which use the mii layer carry the ``mii'' autoconfiguration attribute.  This allows kernel configuration files to sim-
     ply specify PHYs as described above in the synopsis.

     The following is an example of the messages displayed when a network interface with an attached PHY is detected by the kernel:

	   epic0 at pci0 dev 12 function 0: SMC EPIC/100 Fast Ethernet
	   epic0: interrupting at kn20aa irq 4
	   epic0: SMC9432TX, Ethernet address 00:e0:29:07:17:c4
	   qsphy0 at epic0 phy 3: QS6612 10/100 media interface, rev. 1
	   qsphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

     All PHY drivers display the media types supported by the PHY when it is detected by the kernel.  These media types are valid media keywords
     for use with the ifconfig(8) program.

RGEPHY(4)                                                  BSD Kernel Interfaces Manual                                                  RGEPHY(4)

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 advertis-
            ing 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
