RGEPHY(4)	       FreeBSD Kernel Interfaces Manual		     RGEPHY(4)

NAME
     rgephy -- RealTek RTL8168/8169/8110/8211 series 10/100/1000 Gigabit Eth-
     ernet 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 adver-
	    tising 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 autonego-
     tiation:

	   ifconfig re0	media 100baseTX	mediaopt full-duplex,flag0
