+.Sh NAME
+.Nm rgephy
+.Nd RealTek RTL8168/8169/8110/8211 series 10/100/1000 Gigabit Ethernet PHY driver
+.Sh SYNOPSIS
+To compile all available PHY drivers into the kernel,
+place the following line in your kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device miibus"
+.Ed
+.Pp
+Alternatively, to selectively compile this driver into the kernel,
+place the following lines in your kernel configuration file instead:
+.Bd -ragged -offset indent
+.Cd "device mii"
+.Cd "device rgephy"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver supports the RealTek RTL8168, RTL8169, RTL8110 and RTL8211 series
+integrated 10/100/1000 Gigabit Ethernet PHYs.
+.Pp
+In order to get a list of media types and options supported by a specific
+instance of the
+.Nm
+driver, run
+.Li ifconfig -m
+on the instance of its parent MAC driver.
+.Pp
+Additionally,
+the
+.Nm
+driver supports the following special media option:
+.Bl -tag -width ".Cm flag0"
+.It Cm flag0
+When manually setting media type and options via
+.Xr ifconfig 8 ,
+the
+.Nm
+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
+.Nm
+driver allows to turn this behavior off via the
+.Cm flag0
+media option.
+.El
+.Pp
+Note that this special media option will not show up in the output of
+.Xr ifconfig 8 ,
+even when set.
+.Sh EXAMPLES
+Manually set 100BASE-TX full-duplex without also triggering an
+autonegotiation:
+.Pp
+.Dl "ifconfig re0 media 100baseTX mediaopt full-duplex,flag0"
