.SH DESCRIPTION
|
|
.BI ethtool
|
|
is used to query and control network device driver and hardware
|
|
settings, particularly for wired Ethernet devices.
|
|
|
|
.I devname
|
|
is the name of the network device on which ethtool should operate.
|
|
|
|
.SH OPTIONS
|
|
.B ethtool
|
|
with a single argument specifying the device name prints current
|
|
settings of the specified device.
|
|
.TP
|
|
.B \-h \-\-help
|
|
Shows a short help message.
|
|
.TP
|
|
.B \-\-version
|
|
Shows the ethtool version number.
|
|
.TP
|
|
.B \-a \-\-show\-pause
|
|
Queries the specified Ethernet device for pause parameter information.
|
|
.TP
|
|
.B \-A \-\-pause
|
|
Changes the pause parameters of the specified Ethernet device.
|
|
.RS 4
|
|
.TP
|
|
.A2 autoneg on off
|
|
Specifies whether pause autonegotiation should be enabled.
|
|
.TP
|
|
.A2 rx on off
|
|
Specifies whether RX pause should be enabled.
|
|
.TP
|
|
.A2 tx on off
|
|
Specifies whether TX pause should be enabled.
|
|
.RE
|
|
.TP
|
|
.B \-c \-\-show\-coalesce
|
|
Queries the specified network device for coalescing information.
|
|
.TP
|
|
.B \-C \-\-coalesce
|
|
Changes the coalescing settings of the specified network device.
|
|
.TP
|
|
.B \-g \-\-show\-ring
|
|
Queries the specified network device for rx/tx ring parameter information.
|
|
.TP
|
|
.B \-G \-\-set\-ring
|
|
Changes the rx/tx ring parameters of the specified network device.
|
|
.RS 4
|
|
.TP
|
|
.BI rx \ N
|
|
Changes the number of ring entries for the Rx ring.
|
|
.TP
|
|
.BI rx\-mini \ N
|
|
Changes the number of ring entries for the Rx Mini ring.
|
|
.TP
|
|
.BI rx\-jumbo \ N
|
|
Changes the number of ring entries for the Rx Jumbo ring.
|
|
.TP
|
|
.BI tx \ N
|
|
Changes the number of ring entries for the Tx ring.

|
|
.TP
|
|
.B \-i \-\-driver
|
|
Queries the specified network device for associated driver information.
|
|
.TP
|
|
.B \-d \-\-register\-dump
|
|
Retrieves and prints a register dump for the specified network device.
|
|
The register format for some devices is known and decoded others
|
|
are printed in hex.
|
|
When
|
|
.I raw
|
|
is enabled, then ethtool dumps the raw register data to stdout.
|
|
If
|
|
.I file
|
|
is specified, then use contents of previous raw register dump, rather
|
|
than reading from the device.
|
|
.TP
|
|
.B \-e \-\-eeprom\-dump
|
|
Retrieves and prints an EEPROM dump for the specified network device.
|
|
When raw is enabled, then it dumps the raw EEPROM data to stdout. The
|
|
length and offset parameters allow dumping certain portions of the EEPROM.
|
|
Default is to dump the entire EEPROM.

.TP
|
|
.B \-E \-\-change\-eeprom
|
|
If value is specified, changes EEPROM byte for the specified network device.
|
|
offset and value specify which byte and it's new value. If value is not
|
|
specified, stdin is read and written to the EEPROM. The length and offset
|
|
parameters allow writing to certain portions of the EEPROM.
|
|
Because of the persistent nature of writing to the EEPROM, a device-specific
|
|
magic key must be specified to prevent the accidental writing to the EEPROM.
|
|
.TP
|
|
.B \-k \-\-show\-features \-\-show\-offload
|
|
Queries the specified network device for the state of protocol
|
|
offload and other features.
|
|
.TP
|
|
.B \-K \-\-features \-\-offload
|
|
Changes the offload parameters and other features of the specified
|
|
network device. The following feature names are built-in and others
|
|
may be defined by the kernel.
|
|
.RS 4
|
|
.TP
|
|
.A2 rx on off
