RGEPHY(4) FreeBSD 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
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
