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
